A comprehensive guide to writing a compare and contrast essay – key tips and strategies.

Write compare and contrast essay

Writing a compare and contrast essay is a common task for students at various levels of education. This type of essay requires you to analyze similarities and differences between two or more subjects, providing insights and drawing conclusions.

Effective compare and contrast essays go beyond merely listing similarities and differences; they require critical thinking and a coherent structure. In this article, we will explore essential tips and provide examples to help you craft a compelling and well-structured compare and contrast essay.

Understanding the Purpose

Before you start writing a compare and contrast essay, it’s essential to understand the purpose of this type of assignment. The main goal of a compare and contrast essay is to analyze and evaluate the similarities and differences between two or more subjects. By highlighting the similarities and differences, you can provide a deeper understanding of the topics you are comparing. This type of essay allows you to showcase your analytical skills and critical thinking abilities.

By comparing and contrasting different subjects, you can explore various perspectives, draw connections between them, and offer meaningful insights to your readers. Ultimately, the purpose of a compare and contrast essay is not just to point out similarities and differences but to present a compelling argument or thesis that sheds light on the subjects being compared.

Identifying Compare and Contrast Elements

Before you start writing a compare and contrast essay, it’s important to identify the elements that you will be comparing and contrasting. These elements can vary depending on the topic you are exploring, but they generally include:

  • Similarities: These are the aspects of the subjects that are alike or have common characteristics.
  • Differences: These are the aspects of the subjects that are different or have contrasting features.
  • Key Points: These are the main ideas or themes that you will focus on in your comparison and contrast.

Once you have identified these elements, you can use them to structure your essay and create a clear and effective comparison between the subjects you are discussing. By highlighting both the similarities and differences, you can provide a comprehensive analysis that helps your readers understand the relationship between the two subjects.

Tips for Writing a Compare and Contrast Essay

Tips for Writing a Compare and Contrast Essay

Writing a compare and contrast essay can be a challenging task, but with the right approach, it can be a rewarding experience. Here are some tips to help you craft an effective compare and contrast essay:

Choose two subjects that have some similarities and differences to make your essay more interesting and engaging.
Organize your essay into sections for introduction, body paragraphs discussing similarities and differences, and a conclusion.
Decide whether you will compare and contrast point-by-point or use the block method to present your ideas.
Support your arguments with evidence and examples to make your essay more convincing.
Ensure that you spend equal time comparing and contrasting the two subjects to maintain a balanced essay.
Always remember to edit and proofread your essay to eliminate errors and improve clarity.

Organizing Your Ideas

When writing a compare and contrast essay, it is crucial to organize your ideas in a clear and coherent manner. One effective way to structure your essay is to use a block format or a point-by-point format.

In a block format, you discuss one subject entirely, then move on to the next subject. This format allows for a more in-depth analysis of each subject but can make it harder for readers to compare the two subjects directly. On the other hand, in a point-by-point format, you alternate between discussing aspects of each subject in relation to each other. This format makes it easier for readers to see the similarities and differences between the two subjects.

Whichever format you choose, it is essential to have a clear thesis statement that highlights the main points of comparison and contrast. Additionally, make sure to use transitions to guide your readers from one point to the next smoothly.

Consider creating a graphic organizer, such as a Venn diagram or a T-chart, to help you visualize the similarities and differences between the two subjects before you start writing. This can be a helpful tool to ensure that your ideas are well-organized and your essay flows seamlessly.

Using Transitional Words

Transitional words are essential for creating a smooth flow in your compare and contrast essay. They help connect ideas, show relationships between different concepts, and guide the reader through your comparison. Here are some common transitional words to use in your essay:

1. Similarly: Use this word to show similarities between two ideas or concepts. For example, “Similarly, both novels explore themes of love and betrayal.”

2. On the other hand: Use this phrase to introduce a contrasting idea. For instance, “One character is focused on revenge, while, on the other hand, the other character seeks forgiveness.”

3. In contrast: Use this phrase to highlight differences between two ideas. For example, “In contrast to the peaceful countryside, the city is bustling with noise and activity.”

4. Likewise: Use this word to show that a similar point applies to another example. For instance, “Both movies received critical acclaim, and likewise, they were commercial successes.”

By incorporating these transitional words into your essay, you can effectively structure your comparison and make it more coherent for your readers.

Examples of Compare and Contrast Essays

When writing a compare and contrast essay, it can be helpful to see examples of well-crafted essays that effectively compare and contrast two subjects. Here are a few examples:

In this essay, we will compare and contrast the themes of love and betrayal in Shakespeare’s “Romeo and Juliet” and Emily Bronte’s “Wuthering Heights.” Both works explore the complexities of love and the consequences of betrayal, but they do so in very different ways.

This essay will examine the similarities and differences between traditional education and online learning. While both forms of education aim to provide knowledge and skills to students, they vary in terms of accessibility, interaction, and flexibility.

In this essay, we will compare and contrast the economic systems of capitalism and socialism. While both systems involve the distribution of goods and services, they differ in terms of ownership, production, and the role of government.

These examples illustrate how a compare and contrast essay can analyze the similarities and differences between two subjects in a structured and informative way.

Comparing Two Literary Works

Comparing two literary works can be an enriching exercise that allows you to delve deeply into the nuances of each piece. When analyzing two works, it’s important to consider elements such as theme, characterization, setting, and writing style.

Theme: One way to compare two literary works is to examine the central themes present in each piece. Consider how the themes are similar or different and how they are developed throughout the text.

Characterization: Another aspect to compare is the characterization of the main characters in each work. Look at how the characters are portrayed, their motivations, and how they contribute to the overall story.

Setting: The setting of a literary work can also play a significant role in the story. Compare the settings of the two works and consider how they impact the characters and plot.

Writing Style: Finally, analyze the writing styles of the authors in each work. Pay attention to aspects such as tone, language use, and narrative structure to see how they contribute to the overall impact of the text.

By comparing these elements across two literary works, you can gain a deeper understanding of the unique qualities of each piece and appreciate the artistry and skill of the authors.

Contrasting Different Historical Events

Contrasting Different Historical Events

When comparing and contrasting different historical events in your essay, it is essential to highlight the key differences between them. One effective approach is to focus on the causes and consequences of each event, as well as their impact on society and the world at large.

Example: Contrasting the American Revolution with the French Revolution reveals significant differences in terms of their goals and outcomes. While the American Revolution aimed for independence from British rule and emphasized individual rights, the French Revolution sought to overthrow the monarchy and establish a republic based on equality and fraternity. The American Revolution led to the creation of the United States as a democratic nation, while the French Revolution resulted in political instability and the rise of Napoleon Bonaparte.

In your essay, provide specific examples and evidence to support your analysis of different historical events. By contrasting these events effectively, you can demonstrate a deeper understanding of their significance and relevance to the broader historical context.

When should i compare and contrast, making effective comparisons, comparing and contrasting as a brainstorming tool, structuring your comparisons, other interesting articles, frequently asked questions about comparing and contrasting.

Many assignments will invite you to make comparisons quite explicitly, as in these prompts.

  • Compare the treatment of the theme of beauty in the poetry of William Wordsworth and John Keats.
  • Compare and contrast in-class and distance learning. What are the advantages and disadvantages of each approach?

Some other prompts may not directly ask you to compare and contrast, but present you with a topic where comparing and contrasting could be a good approach.

One way to approach this essay might be to contrast the situation before the Great Depression with the situation during it, to highlight how large a difference it made.

Comparing and contrasting is also used in all kinds of academic contexts where it’s not explicitly prompted. For example, a literature review involves comparing and contrasting different studies on your topic, and an argumentative essay may involve weighing up the pros and cons of different arguments.

Prevent plagiarism. Run a free check.

As the name suggests, comparing and contrasting is about identifying both similarities and differences. You might focus on contrasting quite different subjects or comparing subjects with a lot in common—but there must be some grounds for comparison in the first place.

For example, you might contrast French society before and after the French Revolution; you’d likely find many differences, but there would be a valid basis for comparison. However, if you contrasted pre-revolutionary France with Han-dynasty China, your reader might wonder why you chose to compare these two societies.

This is why it’s important to clarify the point of your comparisons by writing a focused thesis statement . Every element of an essay should serve your central argument in some way. Consider what you’re trying to accomplish with any comparisons you make, and be sure to make this clear to the reader.

Comparing and contrasting can be a useful tool to help organize your thoughts before you begin writing any type of academic text. You might use it to compare different theories and approaches you’ve encountered in your preliminary research, for example.

Let’s say your research involves the competing psychological approaches of behaviorism and cognitive psychology. You might make a table to summarize the key differences between them.

Behaviorism Cognitive psychology
Dominant from the 1920s to the 1950s Rose to prominence in the 1960s
Mental processes cannot be empirically studied Mental processes as focus of study
Focuses on how thinking is affected by conditioning and environment Focuses on the cognitive processes themselves

Or say you’re writing about the major global conflicts of the twentieth century. You might visualize the key similarities and differences in a Venn diagram.

A Venn diagram showing the similarities and differences between World War I, World War II, and the Cold War.

These visualizations wouldn’t make it into your actual writing, so they don’t have to be very formal in terms of phrasing or presentation. The point of comparing and contrasting at this stage is to help you organize and shape your ideas to aid you in structuring your arguments.

When comparing and contrasting in an essay, there are two main ways to structure your comparisons: the alternating method and the block method.

The alternating method

In the alternating method, you structure your text according to what aspect you’re comparing. You cover both your subjects side by side in terms of a specific point of comparison. Your text is structured like this:

Mouse over the example paragraph below to see how this approach works.

One challenge teachers face is identifying and assisting students who are struggling without disrupting the rest of the class. In a traditional classroom environment, the teacher can easily identify when a student is struggling based on their demeanor in class or simply by regularly checking on students during exercises. They can then offer assistance quietly during the exercise or discuss it further after class. Meanwhile, in a Zoom-based class, the lack of physical presence makes it more difficult to pay attention to individual students’ responses and notice frustrations, and there is less flexibility to speak with students privately to offer assistance. In this case, therefore, the traditional classroom environment holds the advantage, although it appears likely that aiding students in a virtual classroom environment will become easier as the technology, and teachers’ familiarity with it, improves.

The block method

In the block method, you cover each of the overall subjects you’re comparing in a block. You say everything you have to say about your first subject, then discuss your second subject, making comparisons and contrasts back to the things you’ve already said about the first. Your text is structured like this:

  • Point of comparison A
  • Point of comparison B

The most commonly cited advantage of distance learning is the flexibility and accessibility it offers. Rather than being required to travel to a specific location every week (and to live near enough to feasibly do so), students can participate from anywhere with an internet connection. This allows not only for a wider geographical spread of students but for the possibility of studying while travelling. However, distance learning presents its own accessibility challenges; not all students have a stable internet connection and a computer or other device with which to participate in online classes, and less technologically literate students and teachers may struggle with the technical aspects of class participation. Furthermore, discomfort and distractions can hinder an individual student’s ability to engage with the class from home, creating divergent learning experiences for different students. Distance learning, then, seems to improve accessibility in some ways while representing a step backwards in others.

Note that these two methods can be combined; these two example paragraphs could both be part of the same essay, but it’s wise to use an essay outline to plan out which approach you’re taking in each paragraph.

Some essay prompts include the keywords “compare” and/or “contrast.” In these cases, an essay structured around comparing and contrasting is the appropriate response.

Comparing and contrasting is also a useful approach in all kinds of academic writing : You might compare different studies in a literature review , weigh up different arguments in an argumentative essay , or consider different theoretical approaches in a theoretical framework .

Your subjects might be very different or quite similar, but it’s important that there be meaningful grounds for comparison . You can probably describe many differences between a cat and a bicycle, but there isn’t really any connection between them to justify the comparison.

You’ll have to write a thesis statement explaining the central point you want to make in your essay , so be sure to know in advance what connects your subjects and makes them worth comparing.

Comparisons in essays are generally structured in one of two ways:

  • The alternating method, where you compare your subjects side by side according to one specific aspect at a time.
  • The block method, where you cover each subject separately in its entirety.

It’s also possible to combine both methods, for example by writing a full paragraph on each of your topics and then a final paragraph contrasting the two according to a specific metric.

10.7 Comparison and Contrast

Learning objectives.

  • Determine the purpose and structure of comparison and contrast in writing.
  • Explain organizational methods used when comparing and contrasting.
  • Understand how to write a compare-and-contrast essay.

The Purpose of Comparison and Contrast in Writing

Comparison in writing discusses elements that are similar, while contrast in writing discusses elements that are different. A compare-and-contrast essay , then, analyzes two subjects by comparing them, contrasting them, or both.

The key to a good compare-and-contrast essay is to choose two or more subjects that connect in a meaningful way. The purpose of conducting the comparison or contrast is not to state the obvious but rather to illuminate subtle differences or unexpected similarities. For example, if you wanted to focus on contrasting two subjects you would not pick apples and oranges; rather, you might choose to compare and contrast two types of oranges or two types of apples to highlight subtle differences. For example, Red Delicious apples are sweet, while Granny Smiths are tart and acidic. Drawing distinctions between elements in a similar category will increase the audience’s understanding of that category, which is the purpose of the compare-and-contrast essay.

Similarly, to focus on comparison, choose two subjects that seem at first to be unrelated. For a comparison essay, you likely would not choose two apples or two oranges because they share so many of the same properties already. Rather, you might try to compare how apples and oranges are quite similar. The more divergent the two subjects initially seem, the more interesting a comparison essay will be.

Writing at Work

Comparing and contrasting is also an evaluative tool. In order to make accurate evaluations about a given topic, you must first know the critical points of similarity and difference. Comparing and contrasting is a primary tool for many workplace assessments. You have likely compared and contrasted yourself to other colleagues. Employee advancements, pay raises, hiring, and firing are typically conducted using comparison and contrast. Comparison and contrast could be used to evaluate companies, departments, or individuals.

Brainstorm an essay that leans toward contrast. Choose one of the following three categories. Pick two examples from each. Then come up with one similarity and three differences between the examples.

  • Romantic comedies
  • Internet search engines
  • Cell phones

Brainstorm an essay that leans toward comparison. Choose one of the following three items. Then come up with one difference and three similarities.

  • Department stores and discount retail stores
  • Fast food chains and fine dining restaurants
  • Dogs and cats

The Structure of a Comparison and Contrast Essay

The compare-and-contrast essay starts with a thesis that clearly states the two subjects that are to be compared, contrasted, or both and the reason for doing so. The thesis could lean more toward comparing, contrasting, or both. Remember, the point of comparing and contrasting is to provide useful knowledge to the reader. Take the following thesis as an example that leans more toward contrasting.

Thesis statement: Organic vegetables may cost more than those that are conventionally grown, but when put to the test, they are definitely worth every extra penny.

Here the thesis sets up the two subjects to be compared and contrasted (organic versus conventional vegetables), and it makes a claim about the results that might prove useful to the reader.

You may organize compare-and-contrast essays in one of the following two ways:

  • According to the subjects themselves, discussing one then the other
  • According to individual points, discussing each subject in relation to each point

See Figure 10.1 “Comparison and Contrast Diagram” , which diagrams the ways to organize our organic versus conventional vegetables thesis.

Figure 10.1 Comparison and Contrast Diagram

Comparison and Contrast Diagram

The organizational structure you choose depends on the nature of the topic, your purpose, and your audience.

Given that compare-and-contrast essays analyze the relationship between two subjects, it is helpful to have some phrases on hand that will cue the reader to such analysis. See Table 10.3 “Phrases of Comparison and Contrast” for examples.

Table 10.3 Phrases of Comparison and Contrast

Comparison Contrast
one similarity one difference
another similarity another difference
both conversely
like in contrast
likewise unlike
similarly while
in a similar fashion whereas

Create an outline for each of the items you chose in Note 10.72 “Exercise 1” and Note 10.73 “Exercise 2” . Use the point-by-point organizing strategy for one of them, and use the subject organizing strategy for the other.

Writing a Comparison and Contrast Essay

First choose whether you want to compare seemingly disparate subjects, contrast seemingly similar subjects, or compare and contrast subjects. Once you have decided on a topic, introduce it with an engaging opening paragraph. Your thesis should come at the end of the introduction, and it should establish the subjects you will compare, contrast, or both as well as state what can be learned from doing so.

The body of the essay can be organized in one of two ways: by subject or by individual points. The organizing strategy that you choose will depend on, as always, your audience and your purpose. You may also consider your particular approach to the subjects as well as the nature of the subjects themselves; some subjects might better lend themselves to one structure or the other. Make sure to use comparison and contrast phrases to cue the reader to the ways in which you are analyzing the relationship between the subjects.

After you finish analyzing the subjects, write a conclusion that summarizes the main points of the essay and reinforces your thesis. See Chapter 15 “Readings: Examples of Essays” to read a sample compare-and-contrast essay.

Many business presentations are conducted using comparison and contrast. The organizing strategies—by subject or individual points—could also be used for organizing a presentation. Keep this in mind as a way of organizing your content the next time you or a colleague have to present something at work.

Choose one of the outlines you created in Note 10.75 “Exercise 3” , and write a full compare-and-contrast essay. Be sure to include an engaging introduction, a clear thesis, well-defined and detailed paragraphs, and a fitting conclusion that ties everything together.

Key Takeaways

  • A compare-and-contrast essay analyzes two subjects by either comparing them, contrasting them, or both.
  • The purpose of writing a comparison or contrast essay is not to state the obvious but rather to illuminate subtle differences or unexpected similarities between two subjects.
  • The thesis should clearly state the subjects that are to be compared, contrasted, or both, and it should state what is to be learned from doing so.

There are two main organizing strategies for compare-and-contrast essays.

  • Organize by the subjects themselves, one then the other.
  • Organize by individual points, in which you discuss each subject in relation to each point.
  • Use phrases of comparison or phrases of contrast to signal to readers how exactly the two subjects are being analyzed.

contrast and comparison essay structure

To compare is to examine how things are similar, while to contrast is to see how they differ. A compare and contrast essay therefore looks at the similarities of two or more objects, and the differences. This essay type is common at university, where lecturers frequently test your understanding by asking you to compare and contrast two theories, two methods, two historical periods, two characters in a novel, etc. Sometimes the whole essay will compare and contrast, though sometimes the comparison or contrast may be only part of the essay. It is also possible, especially for short exam essays, that only the similarities or the differences, not both, will be discussed. See the examples below.

  • Compare and contrast Newton's ideas of gravity with those proposed by Einstein ['compare and contrast' essay]
  • Examine how the economies of Spain and China are similar ['compare' only essay]
  • Explain the differences between Achaemenid Empire and Parthian Empire ['contrast' only essay]

There are two main ways to structure a compare and contrast essay, namely using a block or a point-by-point structure. For the block structure, all of the information about one of the objects being compared/contrasted is given first, and all of the information about the other object is listed afterwards. This type of structure is similar to the block structure used for cause and effect and problem-solution essays. For the point-by-point structure, each similarity (or difference) for one object is followed immediately by the similarity (or difference) for the other. Both types of structure have their merits. The former is easier to write, while the latter is generally clearer as it ensures that the similarities/differences are more explicit.

The two types of structure, block and point-by-point , are shown in the diagram below.





Compare and Contrast Structure Words

Compare and contrast structure words are transition signals which show the similarities or differences. Below are some common examples.

  • both... and...
  • not only... but also...
  • neither... nor...
  • just like (+ noun)
  • similar to (+ noun)
  • to be similar (to)
  • to be the same as
  • to be alike
  • to compare (to/with)
  • Computers can be used to communicate easily, for example via email. Similarly/Likewise , the mobile phone is a convenient tool for communication.
  • Both computers and mobile phones can be used to communicate easily with other people.
  • Just like the computer, the mobile phone can be used to communicate easily with other people.
  • The computer is similar to the mobile phone in the way it can be used for easy communication.
  • In contrast
  • In comparison
  • By comparison
  • On the other hand
  • to differ from
  • to be different (from)
  • to be dissimilar to
  • to be unlike
  • Computers, although increasingly small, are not always easy to carry from one place to another. However , the mobile phone can be carried with ease.
  • Computers are generally not very portable, whereas the mobile phone is.
  • Computers differ from mobile phones in their lack of portability.
  • Computers are unlike mobile phones in their lack of portability.

Criteria for comparison/contrast

When making comparisons or contrasts, it is important to be clear what criteria you are using. Study the following example, which contrasts two people. Here the criteria are unclear.

  • Aaron is tall and strong. In contrast , Bruce is handsome and very intelligent.

Although this sentence has a contrast transition , the criteria for contrasting are not the same. The criteria used for Aaron are height (tall) and strength (strong). We would expect similar criteria to be used for Bruce (maybe he is short and weak), but instead we have new criteria, namely appearance (handsome) and intelligence (intelligent). This is a common mistake for students when writing this type of paragraph or essay. Compare the following, which has much clearer criteria (contrast structure words shown in bold).

  • Aaron and Bruce differ in four ways. The first difference is height. Aaron is tall, while Bruce is short. A second difference is strength. Aaron is strong. In contrast , Bruce is weak. A third difference is appearance. Aaron, who is average looking, differs from Bruce, who is handsome. The final difference is intelligence. Aaron is of average intelligence. Bruce, on the other hand , is very intelligent.

Title: There have been many advances in technology over the past fifty years. These have revolutionised the way we communicate with people who are far away. Compare and contrast methods of communication used today with those which were used in the past.

 
         
 
 

Before the advent of computers and modern technology, people communicating over long distances used traditional means such as letters and the telephone. Nowadays we have a vast array of communication tools which can complete this task, ranging from email to instant messaging and video calls. While the present and previous means of communication are similar in their general form , they differ in regard to their speed and the range of tools available . One similarity between current and previous methods of communication relates to the form of communication. In the past, both written forms such as letters were frequently used, in addition to oral forms such as telephone calls. Similarly , people nowadays use both of these forms. Just as in the past, written forms of communication are prevalent, for example via email and text messaging. In addition, oral forms are still used, including the telephone, mobile phone, and voice messages via instant messaging services. However , there are clearly many differences in the way we communicate over long distances, the most notable of which is speed. This is most evident in relation to written forms of communication. In the past, letters would take days to arrive at their destination. In contrast , an email arrives almost instantaneously and can be read seconds after it was sent. In the past, if it was necessary to send a short message, for example at work, a memo could be passed around the office, which would take some time to circulate. This is different from the current situation, in which a text message can be sent immediately. Another significant difference is the range of communication methods. Fifty years ago, the tools available for communicating over long distances were primarily the telephone and the letter. By comparison , there are a vast array of communication methods available today. These include not only the telephone, letter, email and text messages already mentioned, but also video conferences via software such as Skype or mobile phone apps such as WeChat, and social media such as Facebook and Twitter. In conclusion, methods of communication have greatly advanced over the past fifty years. While there are some similarities, such as the forms of communication , there are significant differences, chiefly in relation to the speed of communication and the range of communication tools available . There is no doubt that technology will continue to progress in future, and the advanced tools which we use today may one day also become outdated.

Compare & contrast essays examine the similarities of two or more objects, and the differences.

Cause & effect essays consider the reasons (or causes) for something, then discuss the results (or effects).

Discussion essays require you to examine both sides of a situation and to conclude by saying which side you favour.

Problem-solution essays are a sub-type of SPSE essays (Situation, Problem, Solution, Evaluation).

Transition signals are useful in achieving good cohesion and coherence in your writing.

Tips for Writing a Compare and Contrast Essay

Tips for Writing a Compare and Contrast Essay

  • 19th August 2022

Compare and contrast essays are a specific form of academic essay with unique requirements, so if you’re a student , it’s important that you to know how to write one. Luckily, we’ve pieced together this guide to help you plan, structure, and put together your essay, complete with tips for comparing and contrasting.

Let’s begin.

1. What Is a Compare and Contrast Essay?

As you may have guessed, when writing a compare and contrast essay, you’ll need to do two things:

  • Compare the similarities between two or more given subjects.
  • Contrast their differences.

Compare and contrast essays are a common essay style because they allow your teacher or lecturer to assess your understanding of two theories, research methods, literary techniques, or other subjects. These subjects are usually related and may sometimes be confused with one another or are in conflict with each other.

By comparing and contrasting the subjects, you can also improve your analysis skills .

Some examples of compare and contrast essay titles include:

Compare and contrast a Shakespearean sonnet with a Petrarchan sonnet. What are the similarities and differences between anabolic and catabolic reactions? How were Nehru’s political beliefs similar to Gandhi’s? How did they differ?

2. Planning a Compare and Contrast Essay

As with any essay, before you begin writing, you should have a plan . In this case, you’ll first need to identify the similarities and differences between your subjects.

You can do this by writing out a list of all the qualities each subject possesses. Then, you can pick out any similar qualities that show up in both lists, and any qualities that are unique to just one of them. If you’re a visual learner, you might want to draw this as a Venn diagram .

Once you have all the similarities and differences prepared, consider which of them will be the most useful to include in your essay. Ask yourself:

  • How much can you write about each point?
  • What will your conclusion be, and which points support it?
  • How will each point fit into your essay’s structure?

To answer that last question, let’s take a look at some ways to structure your essay.

3. Structuring a Compare and Contrast Essay

Now that you’ve got a plan for your essay, it’s time to organize it. There are three main structures you can follow when writing a compare and contrast essay: 

  • The block structure: All of the information about one subject (e.g., Shakespearean sonnets) is presented in the first few paragraphs, followed by the subject it’s being compared and contrasted with (e.g., Petrarchan sonnets).
  • The alternating structure: One similarity or difference between both subjects (e.g., rhyme scheme) is explored in one paragraph, followed by a paragraph on another similarity or difference (e.g., use of imagery), and so on.
  • The similarities and differences structure: All the similarities between both subjects are presented, followed by the differences.

There are benefits to each of these structures. The block structure, for example, can be easier to write, while the alternating structure presents each similarity and difference clearly, and the similarities and differences structure focuses on those points rather than the subjects themselves. 

So, when deciding which structure to use, consider what would work best for your essay. If you intend to cover each subject in detail, for example, you might want to choose the block structure. 

On the other hand, if you want to emphasize the connections between each subject, the alternating structure might be best. 

Finally, if you want to conclude that the subjects are either overwhelmingly similar or different to each other, the similarities and differences structure may work in your favor.

Whichever structure you follow, though, you’ll need to include a strong introduction and conclusion.

Your introduction should:

  • Establish the subjects you will be comparing and contrasting.
  • Provide some background about their connection (e.g., “Shakespearean and Petrarchan sonnets are poetic forms common in the 14th to 19th centuries”).
  • Explain what you aim to achieve with your essay.

Meanwhile, your conclusion should:

  • Summarize the main similarities and differences you have identified.
  • Make a point regarding the relationship between your subjects.

4. Things to Remember

Here are some important tips to keep in mind when writing your compare and contrast essay:

  • Ensure you are comparing or contrasting the same criteria between each subject. For example, it wouldn’t make sense to compare the line length of a Shakespearean sonnet with the rhyme scheme of a Petrarchan sonnet, as these are two separate categories.
  • Always address both subjects of your essay in any introductions, conclusions, and topic sentences.
  • Use comparison words and phrases such as “similarly,” “like,” and “in the same way” when comparing subjects.
  • Use contrast words and phrases such as “in contrast,” “however,” and “whereas” when contrasting subjects.
  • As with any essay, make sure to back up any arguments you make with evidence and credible sources .

Writing a Paper: Comparing & Contrasting

A compare and contrast paper discusses the similarities and differences between two or more topics. The paper should contain an introduction with a thesis statement, a body where the comparisons and contrasts are discussed, and a conclusion.

Address Both Similarities and Differences

Because this is a compare and contrast paper, both the similarities and differences should be discussed. This will require analysis on your part, as some topics will appear to be quite similar, and you will have to work to find the differing elements.

Make Sure You Have a Clear Thesis Statement

Just like any other essay, a compare and contrast essay needs a thesis statement. The thesis statement should not only tell your reader what you will do, but it should also address the purpose and importance of comparing and contrasting the material.

Use Clear Transitions

Transitions are important in compare and contrast essays, where you will be moving frequently between different topics or perspectives.

  • Examples of transitions and phrases for comparisons: as well, similar to, consistent with, likewise, too
  • Examples of transitions and phrases for contrasts: on the other hand, however, although, differs, conversely, rather than.

For more information, check out our transitions page.

Structure Your Paper

Consider how you will present the information. You could present all of the similarities first and then present all of the differences. Or you could go point by point and show the similarity and difference of one point, then the similarity and difference for another point, and so on.

Include Analysis

It is tempting to just provide summary for this type of paper, but analysis will show the importance of the comparisons and contrasts. For instance, if you are comparing two articles on the topic of the nursing shortage, help us understand what this will achieve. Did you find consensus between the articles that will support a certain action step for people in the field? Did you find discrepancies between the two that point to the need for further investigation?

Make Analogous Comparisons

When drawing comparisons or making contrasts, be sure you are dealing with similar aspects of each item. To use an old cliché, are you comparing apples to apples?

  • Example of poor comparisons: Kubista studied the effects of a later start time on high school students, but Cook used a mixed methods approach. (This example does not compare similar items. It is not a clear contrast because the sentence does not discuss the same element of the articles. It is like comparing apples to oranges.)
  • Example of analogous comparisons: Cook used a mixed methods approach, whereas Kubista used only quantitative methods. (Here, methods are clearly being compared, allowing the reader to understand the distinction.

Compare and Contrast Essay: Full Writing Guide and 150+ Topics

contrast and comparison essay structure

Compare and contrast essays are academic papers in which a student analyses two or more subjects with each other. To compare means to explore similarities between subjects, while to contrast means to look at their differences. Both subjects of the comparison are usually in the same category, although they have their differences. For example, it can be two movies, two universities, two cars etc.

Good compare and contrast papers from college essay writer focus on a central point, explaining the importance and implications of this analysis. A compare and contrast essay thesis must make a meaningful comparison. Find the central theme of your essay and do some brainstorming for your thesis.

This type of essay is very common among college and university students. Professors challenge their students to use their analytical and comparative skills and pay close attention to the subjects of their comparisons. This type of essay exercises observance and analysis, helps to establish a frame of reference, and makes meaningful arguments about a subject. Let's get deeper on how to write a compare and contrast essay with our research writing services .

How to Start a Compare and Contrast Essay: Brainstorm Similarities and Differences

Now that you know what is compare and contrast essay and are set with your topic, the first thing you should do is grab a piece of paper and make a list with two columns: similarities and differences. Jot down key things first, the most striking ones. Then try to look at the subjects from a different angle, incorporating your imagination.

If you are more of a visual learner, creating a Venn diagram might be a good idea. In order to create it, draw two circles that overlap. In the section where it overlaps, note similarities. Differences should be written in the part of the circle that does not overlap.

Let’s look at a simple example of compare and contrast essay. Let one of the subjects be oranges, and the other one be apples. Oranges have thick peel, originally from India, and are tropical fruit. These characteristics pertain only to oranges and should be in the part of the circle that does not overlap. For the same section on apples, we put thin peel, originated in Turkey or Kazakhstan, and moderate to subtropical. In the section that overlaps, let’s say that they are both fruit, can be juiced, and grow on trees. This simple, yet good example illustrates how the same concept can be applied to many other complicated topics with additional points of comparison and contrast.

Example of compare and contrast

This format of visual aid helps to organize similarities and differences and make them easier to perceive. Your diagram will give you a clear idea of the things you can write about.

Another good idea for brainstorming in preparation for your comparison contrast essay is to create a list with 2 columns, one for each subject, and compare the same characteristics for each of them simultaneously. This compare and contrast format will make writing your comparison contrast paper argument a breeze, as you will have your ideas ready and organized.

One mistake you should avoid is simply listing all of the differences or similarities for each subject. Sometimes students get too caught up in looking for similarities and differences that their compare and contrast essays end up sounding like grocery lists. Your essay should be based on analyzing the similarities and differences, analyzing your conclusions about the two subjects, and finding connections between them—while following a specific format.

Compare and Contrast Essay Structure and Outline

So, how do you structure this compare and contrast paper? Well, since compare and contrast essay examples rely heavily on factual analysis, there are two outline methods that can help you organize your facts. You can use the block method, or point-by-point method, to write a compare and contrast essay outline.

While using the block structure of a compare and contrast essay, all the information is presented for the first subject, and its characteristics and specific details are explained. This concludes one block. The second block takes the same approach as the first for the second subject.

The point-by-point structure lists each similarity and difference simultaneously—making notes of both subjects. For example, you can list a characteristic specific to one subject, followed by its similarity or difference to the other subject.

Both formats have their pros and cons. The block method is clearly easier for a compare and contrast essay writer, as you simply point out all of the information about the two subjects, and basically leave it to the reader to do the comparison. The point-by-point format requires you to analyze the points yourself while making similarities and differences more explicit to the reader for them to be easier to understand. Here is a detailed structure of each type presented below.

Point-by-Point Method

  • Introduce the topic;
  • Specify your theme;
  • Present your thesis - cover all areas of the essay in one sentence.
Example thesis: Cars and motorcycles make for excellent means of transportation, but a good choice depends on the person’s lifestyle, finances, and the city they live in.

Body Paragraph 1 - LIFESTYLE

  • Topic Sentence: Motorcycles impact the owner’s lifestyle less than cars.
  • Topic 1 - Motorcycles
  • ~ Argument: Motorcycles are smaller and more comfortable to store.
  • ~ Argument: Motorcycles are easy to learn and use.
  • Topic 2 - Cars
  • ~ Argument: Cars are a big deal - they are like a second home.
  • ~ Argument: It takes time to learn to become a good driver.

Body Paragraph 2 - FINANCES

  • Topic sentence: Cars are much more expensive than motorcycles
  • ~ Argument: You can buy a good motorcycle for under 300$.
  • ~ Argument: Fewer parts that are more accessible to fix.
  • ~ Argument: Parts and service are expensive if something breaks.
  • ~ Argument: Cars need more gas than motorcycles.

Body Paragraph 3 - CITY

  • Topic sentence: Cars are a better option for bigger cities with wider roads.
  • ~ Argument: Riding motorcycles in a big city is more dangerous than with cars.
  • ~ Argument: Motorcycles work great in a city like Rome, where all the streets are narrow.
  • ~ Argument: Big cities are easier and more comfortable to navigate by car.
  • ~ Argument: With a car, traveling outside of the city is much easier.
  • Sum up all you wrote in the article.

Block Method

  • Thesis — cover all areas of the essay in one sentence

Body Paragraph 1

  • Topic Sentence: Motorcycles are cheaper and easier to take care of than cars.
  • Aspect 1 - Lifestyle
  • Aspect 2 - Finances
  • ~ Argument: Fewer parts, easier to fix.
  • Aspect 3 - City
  • ~ Argument: Riding motorcycles in a big city is more dangerous than cars.

Body Paragraph 2

  • Topic sentence: Cars are more expensive but more comfortable for a big city and for travelling.
  • ~ Argument: Cars are a big deal—like a second home.
  • ~ Argument: With a car, traveling outside the city is much more comfortable.

Body Paragraph 3 ‍

Use the last paragraph to evaluate the comparisons and explain why they’re essential. Giving a lot of facts can be intense. To water it down, try to give the reader any real-life applications of these facts.

Depending on the structure selected, you can begin to create an outline for your essay. The typical comparison essay follows the format of having an introduction, three body paragraphs, and a conclusion — though, if you need to focus on each subject in more detailed ways, feel free to include an extra paragraph to cover all of the most important points.

To make your compare and contrast essay flow better, we recommend using special transition words and phrases. They will add variety and improve your paper overall.

For the section where you compare two subjects, you can include any of the following words: similarly, likewise, also, both, just like, similar to, the same as, alike, or to compare to. When contrasting two subjects, use: in contrast, in comparison, by comparison, on the other hand, while, whereas, but, to differ from, dissimilar to, or unlike.

Show Your Evidence

Arguments for any essay, including compare and contrast essays, need to be supported by sufficient evidence. Make good use of your personal experiences, books, scholarly articles, magazine and newspaper articles, movies, or anything that will make your argument sound credible. For example, in your essay, if you were to compare attending college on campus vs. distance-based learning, you could include your personal experiences of being a student, and how often students show up to class on a daily basis. You could also talk about your experience taking online classes, which makes your argument about online classes credible as well.

Compare and Contrast Essay Examples

Now that you know everything there is to know about compare and contrast essays, let’s take a look at some compare and contrast examples to get you started on your paper or get a hand from our essay helper .

Different countries across the world have diverse cultural practices, and this has an effect on work relationships and development. Geert Hofstede came up with a structured way of comparing cultural dimensions of different countries. The theory explains the impacts of a community’s culture on the values of the community members, and the way these values relate to their behaviors. He gives scores as a way to help distinguish people from different nations using the following dimensions: long-term orientation, individualism, power distance, indulgence, necessity avoidance, and masculinity. Let us examine comparisons between two countries: the United Kingdom and China — based on Hofstede’s Six Dimensions of Culture.
Over the last two decades, the demand from consumers for organic foods has increased tremendously. In fact, the popularity of organic foods has exploded significantly with consumers, spending a considerably higher amount of money on them as compared to the amount spent on inorganic foods. The US market noted an increase in sales of more than 10% between 2014 and 2015 (Brown, n.p). The increase is in line with the views of many consumers that organic foods are safer, tastier, and healthier compared to the inorganic foods. Furthermore, considering the environmental effects of foods, organic foods present less risk of environmental pollution — compared to inorganic foods. By definition, organic foods are those that are grown without any artificial chemical treatment, or treatment by use of other substances that have been modified genetically, such as hormones and/or antibiotics (Brown, n.p).

Finding the Best Compare and Contrast Essay Topics For You

When choosing a topic for your comparison essay, remember that subjects cannot be drastically different, because there would be little to no points of comparison (similarities). The same goes for too many similarities, which will result in poor contrasts. For example, it is better to write about two composers, rather than a composer and a singer.

It is extremely important to choose a topic you are passionate about. You never want to come across something that seems dull and uninspiring for you. Here are some excellent ways to brainstorm for a topic from essay writer :

  • Find categories: Choose a type (like animals, films or economics), and compare subjects within that category – wild animals to farm animals, Star Wars to Star Trek, private companies to public companies, etc.
  • Random Surprising Fact: Dig for fun facts which could make great topics. Did you know that chickens can be traced back to dinosaurs?
  • Movie vs. Book: Most of the time, the book is better than the movie — unless it’s Blade Runner or Lord of the Rings. If you’re a pop culture lover, compare movies vs. books, video games, comics, etc.

How to Choose a Great Compare and Contrast Topic

College students should consider providing themselves with a chance to use all topic examples. With enough revision, an advantage is gained. As it will be possible to compare arguments and contrast their aspects. Also, discuss numerous situations to get closer to the conclusion.

For example:

  • Choose a topic from the field of your interests. Otherwise you risk failing your paper.
  • It is a good idea to choose a topic based upon the class subject or specialist subject. (Unless the requirements say otherwise.)
  • Analyze each argument carefully. Include every detail for each opposing idea. Without doing so, you can definitely lower grades.
  • Write a conclusion that summarizes both arguments. It should allow readers to find the answer they’re looking for.
  • It is up to you to determine which arguments are right and wrong in the final conclusion.
  • Before approaching the final conclusion, it’s important to discuss each argument equally. It is a bad idea to be biased, as it can also lower grades.

  • Writing for Success: Compare/Contrast

LEARNING OBJECTIVES

This section will help you determine the purpose and structure of comparison/contrast in writing.

The Purpose of Compare/Contrast in Writing

Comparison in writing discusses elements that are similar, while contrast in writing discusses elements that are different. A compare-and-contrast essay, then, analyzes two subjects by comparing them, contrasting them, or both.

The key to a good compare-and-contrast essay is to choose two or more subjects that connect in a meaningful way. The purpose of conducting the comparison or contrast is not to state the obvious but rather to illuminate subtle differences or unexpected similarities. For example, if you wanted to focus on contrasting two subjects you would not pick apples and oranges; rather, you might choose to compare and contrast two types of oranges or two types of apples to highlight subtle differences. For example, Red Delicious apples are sweet, while Granny Smiths are tart and acidic. Drawing distinctions between elements in a similar category will increase the audience’s understanding of that category, which is the purpose of the compare-and-contrast essay.

Similarly, to focus on comparison, choose two subjects that seem at first to be unrelated. For a comparison essay, you likely would not choose two apples or two oranges because they share so many of the same properties already. Rather, you might try to compare how apples and oranges are quite similar. The more divergent the two subjects initially seem, the more interesting a comparison essay will be.

The Structure of a Compare/Contrast Essay

The compare-and-contrast essay starts with a thesis that clearly states the two subjects that are to be compared, contrasted, or both and the reason for doing so. The thesis could lean more toward comparing, contrasting, or both. Remember, the point of comparing and contrasting is to provide useful knowledge to the reader. Take the following thesis as an example that leans more toward contrasting:

Thesis Statement: Organic vegetables may cost more than those that are conventionally grown, but when put to the test, they are definitely worth every extra penny.

Here the thesis sets up the two subjects to be compared and contrasted (organic versus conventional vegetables), and it makes a claim about the results that might prove useful to the reader.

You may organize compare-and-contrast essays in one of the following two ways:

  • According to the subjects themselves, discussing one then the other
  • According to individual points, discussing each subject in relation to each point

The organizational structure you choose depends on the nature of the topic, your purpose, and your audience.

Given that compare-and-contrast essays analyze the relationship between two subjects, it is helpful to have some phrases on hand that will cue the reader to such analysis.

Phrases of Comparison and Contrast

one similarity

one difference
another similarity another difference
both conversely
like in contrast
likewise unlike
similarly while
in a similar fashion whereas

Writing an Compare/Contrast Essay

First choose whether you want to compare seemingly disparate subjects, contrast seemingly similar subjects, or compare and contrast subjects. Once you have decided on a topic, introduce it with an engaging opening paragraph. Your thesis should come at the end of the introduction, and it should establish the subjects you will compare, contrast, or both as well as state what can be learned from doing so.

The body of the essay can be organized in one of two ways: by subject or by individual points. The organizing strategy that you choose will depend on, as always, your audience and your purpose. You may also consider your particular approach to the subjects as well as the nature of the subjects themselves; some subjects might better lend themselves to one structure or the other. Make sure to use comparison and contrast phrases to cue the reader to the ways in which you are analyzing the relationship between the subjects.

After you finish analyzing the subjects, write a conclusion that summarizes the main points of the essay and reinforces your thesis.

Compare/Contrast Essay Example

Comparing and Contrasting London and Washington, DC

By Scott McLean in Writing for Success

Both Washington, DC, and London are capital cities of English-speaking countries, and yet they offer vastly different experiences to their residents and visitors. Comparing and contrasting the two cities based on their history, their culture, and their residents show how different and similar the two are.

Both cities are rich in world and national history, though they developed on very different time lines. London, for example, has a history that dates back over two thousand years. It was part of the Roman Empire and known by the similar name, Londinium. It was not only one of the northernmost points of the Roman Empire but also the epicenter of the British Empire where it held significant global influence from the early sixteenth century on through the early twentieth century. Washington, DC, on the other hand, has only formally existed since the late eighteenth century. Though Native Americans inhabited the land several thousand years earlier, and settlers inhabited the land as early as the sixteenth century, the city did not become the capital of the United States until the 1790s. From that point onward to today, however, Washington, DC, has increasingly maintained significant global influence. Even though both cities have different histories, they have both held, and continue to hold, significant social influence in the economic and cultural global spheres.

Both Washington, DC, and London offer a wide array of museums that harbor many of the world’s most prized treasures. While Washington, DC, has the National Gallery of Art and several other Smithsonian galleries, London’s art scene and galleries have a definite edge in this category. From the Tate Modern to the British National Gallery, London’s art ranks among the world’s best. This difference and advantage has much to do with London and Britain’s historical depth compared to that of the United States. London has a much richer past than Washington, DC, and consequently has a lot more material to pull from when arranging its collections. Both cities have thriving theater districts, but again, London wins this comparison, too, both in quantity and quality of theater choices. With regard to other cultural places like restaurants, pubs, and bars, both cities are very comparable. Both have a wide selection of expensive, elegant restaurants as well as a similar amount of global and national chains. While London may be better known for its pubs and taste in beer, DC offers a different bar-going experience. With clubs and pubs that tend to stay open later than their British counterparts, the DC night life tend to be less reserved overall.

Both cities also share and differ in cultural diversity and cost of living. Both cities share a very expensive cost of living—both in terms of housing and shopping. A downtown one-bedroom apartment in DC can easily cost $1,800 per month, and a similar “flat” in London may double that amount. These high costs create socioeconomic disparity among the residents. Although both cities’ residents are predominantly wealthy, both have a significantly large population of poor and homeless. Perhaps the most significant difference between the resident demographics is the racial makeup. Washington, DC, is a “minority majority” city, which means the majority of its citizens are races other than white. In 2009, according to the US Census, 55 percent of DC residents were classified as “Black or African American” and 35 percent of its residents were classified as “white.” London, by contrast, has very few minorities—in 2006, 70 percent of its population was “white,” while only 10 percent was “black.” The racial demographic differences between the cities is drastic.

Even though Washington, DC, and London are major capital cities of English-speaking countries in the Western world, they have many differences along with their similarities. They have vastly different histories, art cultures, and racial demographics, but they remain similar in their cost of living and socioeconomic disparity.

How to Structure an Essay

essay structure

Essay writing is a fundamental skill, a basic task, that is expected of those who choose to pursue their undergraduate and master’s degrees. It constitutes a key requirement for students to complete a given course credit. However, many students and early career researchers find themselves struggling with the challenge of organizing their thoughts into a coherent, engaging structure. This article is especially for those who see essay writing as a daunting task and face problems in presenting their work in an impactful way.  

Table of Contents

  • Writing an essay: basic elements and some key principles  
  • Essay structure template 
  • Chronological structure 
  • Problem-methods-solutions structure 
  • Compare and contrast structures 
  • Frequently asked questions on essay structure 

Read on as we delve into the basic elements of essay writing, outline key principles for organizing information, and cover some foundational features of writing essays.  

Writing an essay: basic elements and some key principles

Essays are written in a flowing and continuous pattern but with a structure of its own. An introduction, body and conclusion are integral to it. The key is to balance the amount and kind of information to be presented in each part. Various disciplines may have their own conventions or guidelines on the information to be provided in the introduction.  

A clear articulation of the context and background of the study is important, as is the definition of key terms and an outline of specific models or theories used. Readers also need to know the significance of the study and its implications for further research. Most importantly, the thesis or the main proposition should be clearly presented.  

The body of the essay is therefore organized into paragraphs that hold the main ideas and arguments and is presented and analyzed in a logical manner. Ideally, each paragraph of the body focuses on one main point or a distinct topic and must be supported by evidence and analysis. The concluding paragraph should bring back to the reader the key arguments, its significance and food for thought. It is best not to re-state all the points of the essay or introduce a new concept here. 

In other words, certain general guidelines help structure the information in the essay. The information must flow logically with the context or the background information presented in the introductory part of the essay. The arguments are built organically where each paragraph in the body of the essay deals with a different point, yet closely linked to the para preceding and following it. Importantly, when writing essays, early career researchers must be careful in ensuring that each piece of information relates to the main thesis and is a building block to the arguments. 

Essay structure template

  • Introduction 
  • Provide the context and share significance of the study 
  • Clearly articulate the thesis statement 
  • Body  
  • Paragraph 1 consisting of the first main point, followed by supporting evidence and an analysis of the findings. Transitional words and phrases can be used to move to the next main point. 
  • There can be as many paragraphs with the above-mentioned elements as there are points and arguments to support your thesis. 
  • Conclusion  
  • Bring in key ideas and discuss their significance and relevance 
  • Call for action 
  • References 

Essay structures

The structure of an essay can be determined by the kind of essay that is required.  

Chronological structure

Also known as the cause-and-effect approach, this is a straightforward way to structure an essay. In such essays, events are discussed sequentially, as they occurred from the earliest to the latest. A chronological structure is useful for discussing a series of events or processes such as historical analyses or narratives of events. The introduction should have the topic sentence. The body of the essay should follow a chorological progression with each para discussing a major aspect of that event with supporting evidence. It ends with a summarizing of the results of the events.  

Problem-methods-solutions structure

Where the essay focuses on a specific problem, the problem-methods-solutions structure can be used to organize the essay. This structure is ideal for essays that address complex issues. It starts with presenting the problem, the context, and thesis statement as introduction to the essay. The major part of the discussion which forms the body of the essay focuses on stating the problem and its significance, the author’s approach or methods adopted to address the problem along with its relevance, and accordingly proposing solution(s) to the identified problem. The concluding part offers a recap of the research problem, methods, and proposed solutions, emphasizing their significance and potential impact. 

Compare and contrast structures

This structure of essay writing is ideally used when two or more key subjects require a comparison of ideas, theories, or phenomena. The three crucial elements, introduction, body, and conclusion, remain the same. The introduction presents the context and the thesis statement. The body of the essay seeks to focus on and highlight differences between the subjects, supported by evidence and analysis. The conclusion is used to summarize the key points of comparison and contrast, offering insights into the significance of the analysis.  

Depending on how the subjects will be discussed, the body of the essay can be organized according to the block method or the alternating method. In the block method, one para discusses one subject and the next para the other subject. In the alternative method, both subjects are discussed in one para based on a particular topic or issue followed by the next para on another issue and so on.  

Frequently asked questions on essay structure

An essay structure serves as a framework for presenting ideas coherently and logically. It comprises three crucial elements: an introduction that communicates the context, topic, and thesis statement; the body focusing on the main points and arguments supported with appropriate evidence followed by its analysis; and a conclusion that ties together the main points and its importance .  

An essay structure well-defined essay structure enhances clarity, coherence, and readability, and is crucial for organizing ideas and arguments to effectively communicate key aspects of a chosen topic. It allows readers to better understand arguments presented and demonstrates the author’s ability to organize and present information systematically. 

Yes, while expert recommend following an essay structure, early career researchers may choose how best to adapt standard essay structures to communicate and share their research in an impactful and engaging way. However, do keep in mind that deviating too far from established structures can hinder comprehension and weaken the overall effectiveness of the essay,  By understanding the basic elements of essay writing and employing appropriate structures such as chronological, problem-methods-solutions, or compare and contrast, researchers can effectively organize their ideas and communicate their findings with clarity and precision.

How to Write a Compare and Contrast Essay

Published September 27, 2020. Updated May 4, 2022.

Compare and Contrast Essay Definition

A compare and contrast essay discusses similarities and differences between two subjects. The discussion shows the writer’s deep understanding of both subjects.

Overview of a Compare and Contrast Essay

  • Choose what two subjects to compare and contrast.
  • Brainstorm similarities and differences between the two subjects.
  • Develop a thesis statement and write an introduction.
  • Write an analysis, using the block method or the point-by-point method.
  • Write a conclusion.

This page will cover the following points:

Key Takeaways

What is a compare and contrast essay, step 1: choose what to compare and contrast, step 2: brainstorm similarities and differences, step 3: write an introduction and a thesis, step 4: use block method or point-to-point, step 5: write a conclusion.

  • Why Do Teachers Assign Compare and Contrast Essays?
  • A compare and contrast essay discusses the similarities and differences between two subjects to show a deep understanding of both.
  • Pick subjects and points that are relevant to your class .
  • Use your essay’s thesis statement to show the reader why the similarities and differences are important.
  • Choose whether you’d like to focus on one subject at a time ( block method ) or move back and forth between subjects ( point-to-point method ).
  • A  compare and contrast essay outline includes a full thesis statement and uses appropriate structure ( block method or point-to-point ).
  • A  thesis statement is the foundation of an essay, listing your paper’s main comparisons and explaining why they’re important.
  • With  block structure , you dedicate each body paragraph to one of your two subjects.
  • With  point-to-point , you dedicate each body paragraph to one of your main points about both subjects.

A compare and contrast essay discusses the similarities and differences between two subjects. This shows a deep understanding of both subjects.

Sometimes, instructors ask students to weigh the positives and negatives of both subjects, choose which subject is better, and defend their position. Read the essay prompt carefully!

Worried about your writing? Submit your paper for a Chegg Writing essay check , or for an Expert Check proofreading . Both can help you find and fix potential writing issues.

In some classes, your instructor will tell you which two subjects to focus on. They’ll usually pick topics discussed in lectures.

For example, in an American literature course, your instructor may ask you to compare and contrast two writers like Allen Ginsberg and Jack Kerouac. Both were part of the same literary movement (the Beat Generation) but still had unique styles and priorities.

Your instructor may let you choose your subjects. Pick two people, things, or ideas discussed in class with clear differences but something in common, too.

Let’s say, for example, your class is talking about pizza (what a great class, right?). You’ll want to choose two subjects in that category that are comparable, such as New York-style pizza and Chicago deep-dish pizza. Both are types of pizza, and they both mean a lot to certain American cities.

You can also find ways to contrast these two pizzas. They both have a distinct shape and are eaten differently (try eating deep-dish pizza with your hands!).

Although your class probably isn’t talking about pizza, the point here is to pick two subjects that:

  • Your instructor or textbook discussed.
  • You feel confident about and which have several important similarities and differences.

But how will you know if any given similarity or difference is important ? In the next section, you’ll brainstorm your essay’s main points and pick the ones that are most appropriate for your class.

By now, you’ve chosen (or were told) your two subjects. Next, it’s time to think about what differences and similarities your paper should focus on.

Since this brainstorming session is just for you, feel free to use whichever method you prefer. Some people like to use Venn diagrams to organize their thoughts. Others prefer a T-chart or just jotting ideas down.

Not all compare and contrast points are made equal. Think about what your instructor has talked about in class so far. Then, decide which points would sound the most appropriate for your course.

This is also a good time to revisit the prompt. Your instructor may have already hinted at what they’d like you to discuss in the instructions.

Here’s an example of a brainstorming session about New York- and Chicago-style pizza. Let’s figure out which of these compare and contrast points would be best for the paper:

Point #1: Because of the size, often sold by the slice, it is a quick fast-food option Point #1: Mostly sold by the pie, making it more common for “sit-down” restaurants or at-home cooking
Point #2: Hand-tossed crust Point #2: Thick, deep crust
Point #3: Important for NYC’s identity Point #3: Important for Chicago’s identity
Point #4: Many restaurants nearby make it Point #4: Many restaurants nearby make it

After brainstorming, you have four very different points for your pizza paper. Each could be helpful, depending on the class.

If the class is about local history, then the last point, “many restaurants nearby make it,” will be useful. If not, then that point is likely the least relevant.

Meanwhile, a class about United States history will care deeply about how these different foods helped shape the identity of Chicago and New York City, respectively (point #3).

Points #1 and #2 talk about the size and shape of the pizza. These would be great choices for a home economics class, where the preparation and presentation of the dish are important.

Whichever points you choose for your compare and contrast essay, make sure they make sense and seem relevant to your class. Never throw in an extra point just to reach the word count for the paper. Your instructor will be able to tell!

Once you have three or four relevant points for your compare and contrast essay, it’s time to write the thesis statement. This will tell your instructor why these similarities and differences are important and worth talking about in an essay.

The introduction is where you’ll tell your audience what your two subjects are. You’ll also discuss the main ways you plan to compare and contrast them.

One of the most important parts of your introduction (and the whole paper) is your thesis statement. The thesis is the main argument of your essay.

Why should someone care about the similarities and differences between these two subjects? That’s the question your thesis statement should answer.

Let’s think, for example, about the New York- and Chicago-style pizza essay. Why should your instructor care about comparing and contrasting these two pizza types?

Here’s an example thesis statement for that paper:

Both New York-style and Chicago deep-dish pizza are important to the identities of their respective cities. However, the fast, portable nature of by-the-slice New York-style pizza makes it easier for the average New Yorker to eat frequently than does the deep-dish pizza for Chicago residents.

This thesis statement not only points out differences and similarities between the pizzas but also begins to say why those differences matter. Remember that the rest of your paper should support the points made in your thesis statement and address important questions.

For example, in the pizza-paper thesis, common questions might include:

What makes New York-style pizza more portable? In what ways are these pizzas important to each city’s identity?

Now, you have a compelling thesis statement for your paper ready to go. Next, you’ll spend some time thinking about how you want to present the similarities and differences between your two subjects.

Would you like to talk about one subject at a time? Or would you prefer to switch between the two to better highlight their differences?

In the next section, you’ll learn the pros and cons of both of these styles. Then, you’ll decide which one is right for your paper.

Here’s what a well-outlined introduction looks like:

– Begin with a lighthearted discussion about the centuries-long debate over cats and dogs.

– Thesis statement: Cats and dogs have varying activity levels, maintenance needs, and ways of showing affection, which potential owners should keep in mind before deciding between the two.

There are many ways to format your compare and contrast paper. But to keep things simple, let’s focus on the two most popular strategies.

With the block method , you make all your points about subject #1 before switching to subject #2. You may dedicate one or even two full paragraphs to the first subject before comparing it with the second one.

Here’s an example outline for a block method essay:

Paragraph 1: Introduction

P2: Subject #1

P3: Subject #1 (continued)

P4: Subject #2

P5: Subject #2 (continued)

P6: Conclusion

There are pros and cons to each method. The main benefit of the block method is that it is easy to keep your paper organized. Because you’re only discussing one subject at a time, your instructor can easily tell what you’re talking about.

There are still cons to this structure, though. For example, it will be harder for your audience to remember the points you made about subject #1 when you finally get to subject #2.

If you want to more closely compare and contrast your two subjects, you’ll want to use the point-to-point approach.

With point-to-point, you’ll dedicate each of your body paragraphs to a similarity or difference between the two subjects. You’ll compare and contrast both subjects in each body paragraph.

Let’s take a look at an outline organized for the point-to-point method:

P2: Similarity #1

P3: Similarity #2

P4: Difference #1

P5: Difference #2

The main benefit of point-to-point is that the similarities and differences between your two subjects will be more clear. After all, you’re going back and forth between the two at all times.

Because you are switching so often, though, you’ll want to write very clearly. Be sure to use plenty of transition words, which you’ll learn more about in the next section. Otherwise, your instructor may lose track of what you’re discussing.

Both of these methods will work with most compare and contrast essays. You’ll have to decide for yourself if you feel your subjects would be better discussed one at a time (block method) or back and forth (point-to-point).

Template on block structure and point-to-point examples

Transition words for a compare and contrast essay.

In a compare and contrast essay, you’ll be discussing at least two different subjects throughout the paper. That’s why it’s helpful to use transition words. These words will let your audience know when you’re moving on to a new topic or directly contrasting two ideas.

Here are some useful transition words for compare and contrast essays:

  • in contrast

As you can guess, some of these words (ex: “similarly” and “likewise”) help you compare your two subjects. Here’s an example:

Pizza-by-the-slice places are an iconic image of New York City. Similarly , visitors to Chicago make it a point to find a deep-dish pizza restaurant.

Other transition words (ex: “in contrast” and “unlike”) point to an important difference. Let’s try one out:

Unlike New York-style pizza, which can be enjoyed on the go, Chicago deep-dish pizza is suited better for a traditional, sit-down restaurant.

Use these and other transition words to make your points more clear. Try using different transition words throughout your paper, such as using “similarly” once and then “likewise” the next time. That way, you can avoid monotonous sentences.

By the time you reach the conclusion of a compare and contrast paper, you’ve already done a lot of planning and writing. It’s completely understandable if you feel a bit burned out.

Like many other papers, you’ll want to use the conclusion of your compare and contrast essay to remind your instructor of your main points. But it’s also important not to copy and paste your introduction into the conclusion.

Try to find a new, eye-catching way to transition back into your main points and restate your thesis. Here’s an example for the New York- and Chicago-style pizzas:

In the season 2 episode of The Office (US), “Valentine’s Day,” Michael Scott visits downtown New York City and immediately runs into a Sbarro’s restaurant for a “New York slice.” The scene is a joke about Michael’s naïveté. But it also points to how second nature New York-style pizza is for experiencing the area. Both New York-style and Chicago deep-dish pizza hold a special place in their city’s identities…

As always, make sure whatever you write is appropriate for your class. With a topic as light-hearted as pizza, a quick The Office reference fits right in. But in other essays, a pop culture reference would be distracting.

Here’s an example of an outline for a conclusion:

– Talk about famous cats and dogs in pop culture and their personalities, like Chloe and Max from The Secret Life of Pets .

–  Restate thesis: From the palaces of Ancient Egypt to the condos of modern-day New York City, both cats and dogs have long been revered for their companionship. Potential owners should consider cats and dogs’ varying activity levels, grooming needs, and ways of showing affection before deciding which pet is right for them.

Use your conclusion to reinforce the points made throughout the paper. Adding anecdotes like the one above can make your paper stand out and keep the attention of your instructor. It’s also a way to let them know that you took the assignment seriously from the beginning to the very end.

Before you turn in that paper, don’t forget to cite your sources in APA format , MLA format , or a style of your choice.

Why Do Teachers assign Compare and Contrast Essays?

In many cases, your instructor assigns compare and contrast papers to test your comprehension of two subjects, as well as to see how well you understand authors, historical periods, or other concepts discussed in class.

Planning and writing these essays can be intimidating at first. In this guide, though, you’ll find helpful tips, from the first brainstorming session all the way to wrapping up the conclusion.

Governance and Cuisine: the Flavors of Constitutional Republics and Democracies

This essay explores the similarities and differences between constitutional republics and democracies through the lens of gourmet cuisine. It compares a constitutional republic to a meticulously crafted French pastry, emphasizing stability and adherence to a defined set of principles outlined in a constitution. In contrast, democracy is likened to a vibrant street food market, highlighting the responsiveness and adaptability of a system that reflects the will of the people. The essay examines how countries like the United Kingdom and India blend elements of both governance models, much like fusion cuisine combines different culinary traditions. By understanding these parallels, the essay provides insights into the complexities and dynamics of political systems.

How it works

Understanding constitutional republics and democracies can be as delightful and complex as exploring the world of gourmet cuisine. Just as different culinary traditions offer unique flavors and experiences, these forms of governance present distinct approaches to organizing and managing society. Let’s embark on a journey to compare these governance models through the lens of culinary arts.

Imagine a constitutional republic as a meticulously crafted French pastry. The process of creating a perfect croissant, for instance, requires a precise recipe, quality ingredients, and expert techniques.

Similarly, a constitutional republic is grounded in a carefully designed constitution that outlines the structure of government, delineates powers, and guarantees rights. This document is akin to a trusted recipe that ensures consistency, stability, and the protection of individual liberties. The United States serves as a prime example, where the Constitution acts as the guiding principle for all governmental actions, much like the detailed steps followed by a pastry chef.

In this system, the rule of law is paramount, ensuring that every action by the government adheres to the constitutional framework. This adherence provides stability and predictability, much like the reliable perfection of a well-made croissant. The separation of powers within a constitutional republic functions like the balanced ingredients in a recipe, each element—be it the executive, legislative, or judicial branch—playing a critical role in creating a harmonious whole. This balance prevents any single branch from overpowering the others, ensuring a well-rounded and stable governance structure.

On the other hand, democracy can be compared to a vibrant, bustling street food market. Imagine the lively atmosphere of a Thai street food market, where the air is filled with tantalizing aromas, and each vendor offers a unique and flavorful dish. In ancient Athens, direct democracy allowed citizens to participate directly in legislative and judicial decisions, much like the spontaneous and dynamic interactions at a street market. Modern representative democracies, where elected officials act on behalf of the people, resemble a collaborative kitchen where chefs work together to create a diverse menu, each bringing their own flair and expertise to the table.

Democracies prioritize the role of the people, ensuring that the will of the majority is reflected in government decisions. This responsiveness is akin to the adaptability of street food vendors who cater to the immediate tastes and preferences of their customers. However, without a guiding framework, democracies can risk majoritarianism, where the majority’s desires might overshadow the rights of minority groups. This potential for imbalance highlights the importance of blending democratic principles with constitutional safeguards, much like balancing bold flavors with underlying subtleties in a well-composed dish.

Consider the United Kingdom, a nation that masterfully blends elements of both governance models, much like a fusion restaurant combining different culinary traditions. Operating as a parliamentary democracy with a constitutional monarchy, the UK offers the stability of a constitutional framework with the flexibility of democratic responsiveness. The British Parliament, like a dynamic kitchen staff, debates and decides on laws, while the monarchy provides a sense of continuity and tradition, akin to a signature dish that anchors the menu. This hybrid system ensures governance that is both adaptable and grounded in established principles.

Similarly, India operates as a federal parliamentary democratic republic, with its Constitution serving as a comprehensive guide for governance. The Indian Constitution, much like a detailed cookbook, outlines the powers and responsibilities of government institutions and protects individual rights. Elected representatives, like chefs interpreting a recipe, bring their constituents’ diverse perspectives into the legislative process, creating a vibrant and multifaceted political landscape. This combination allows for both stability and responsiveness, much like a well-curated menu that offers both classic and innovative dishes.

In essence, the distinctions between constitutional republics and democracies can be likened to the differences between a meticulously crafted pastry and the dynamic variety of street food. A constitutional republic, with its emphasis on the rule of law and protection of individual rights, offers stability and predictability. Democracy, with its focus on the will of the people, provides flexibility and responsiveness. The interplay between these two models can be seen in various countries around the world, where elements of both systems are combined to create a balanced and effective form of governance.

Think of the art of Japanese kaiseki, where a multi-course meal balances taste, texture, and presentation with meticulous precision. A constitutional republic is similar, with laws and institutions shaping the direction of governance within a structured framework. In contrast, the spontaneous creation of a food festival, responding to seasonal ingredients and current trends, mirrors the fluid and responsive nature of a democracy. Both culinary traditions require skill and intuition, and both governance models require a balance of principles and adaptability.

Understanding these nuances requires a keen appreciation for the interplay between structure and flexibility, whether in the context of political systems or culinary arts. Just as a gourmand must understand different cuisines to fully appreciate a meal, citizens must understand the principles and dynamics of their government to engage effectively in civic life. The art of governance, much like the art of cuisine, is diverse and multifaceted, offering numerous ways to achieve a harmonious and prosperous society.

In conclusion, comparing constitutional republics and democracies through the lens of cuisine highlights their unique characteristics and the potential for blending elements to create a balanced governance system. Whether as a meticulously crafted pastry or a vibrant street food market, each model has its strengths and challenges. By appreciating these differences and recognizing the potential for hybrid systems, we can better understand the intricate dance of governance and the ongoing pursuit of a just and effective society, much like savoring the complexity and richness of a well-prepared meal.
