Writing effective comparative essays requires strategic techniques and thoughtful consideration of common pitfalls. A comparative essay explores the similarities and differences between subjects, allowing the writer to draw conclusions related to the topics of the material.

This article outlines key strategies, such as using transitions, incorporating evidence, and maintaining a formal tone. It also identifies mistakes to avoid, like failing to establish a clear basis for comparison or providing a superficial analysis.

The article emphasizes the importance of revising your comparative essay. This process enables you to refine your analysis, strengthen your arguments, and enhance the overall quality of your work. Incorporating feedback from peers or instructors can elevate your comparative essay and communicate your unique insights more effectively.

Whether you are a student or a professional writer, this guidance can help you craft comparative essays that captivate and inform your audience. Let’s explore the essentials of comparative analysis to enhance your writing prowess.

What is a Comparative Essay?

A comparative essay is a form of academic writing that examines and analyzes two or more subjects, identifying their similarities and differences. This type of essay allows students to develop critical thinking skills by evaluating and contrasting various topic elements. 

For example, a comparative analysis of the Roman Empire and the Aztec Empire might make a good history class topic. In contrast, a comparative study of the Harlem Renaissance and the Chicano Art Movement would make a good art class focus. 

Types of Comparative Methods

There are two main methods of structuring a comparative essay: the block method and the point-by-point method.

Block Method

• In the block method , you discuss each subject separately.
• You spend one or more paragraphs focusing on the first subject, then move on to the second subject.
• This allows you to go into more detail about each subject before comparing.
• The block method is good when the subjects you’re comparing have many differences or when you want to establish a strong foundation for your comparison.

Point-by-Point Method

• The point-by-point method jumps back and forth between the two subjects.
• In each paragraph, you address a specific point of comparison or contrast between the subjects.
• This structure encourages you to compare the subjects directly, clearly highlighting their similarities and differences.
• The point-by-point method works well when the subjects share clear, significant points of comparison, allowing you to explore their differences and similarities efficiently.

Why are Comparative Essays Important?

Comparative essays are an important part of academic writing because they encourage students to engage in deeper analysis, identify meaningful connections, and better understand the subjects being explored. 

By comparing and contrasting different concepts, ideas, or phenomena, students can develop a well-rounded perspective and strengthen their ability to think critically.

What Should You Consider When Selecting Topics for Comparison?

When choosing topics for a comparative essay, it’s important to select subjects with some common ground but distinct differences. This will allow you to conduct a meaningful analysis and draw insightful conclusions. Consider factors such as the subjects’ historical context, cultural influences, or underlying themes to ensure a productive comparison.

For example, using the Block Method, you might do the following;

• Comparing the education systems in the United States and Canada
• Analyzing the differences between classic literature and modern young adult novels
• Contrasting the architectural styles of Gothic cathedrals and Renaissance palaces

In a block method essay on these topics, the writer would devote one or more paragraphs to thoroughly describing and analyzing the first subject (e.g., the US education system, classic literature, Gothic cathedrals) before moving on to discuss the second subject (e.g., the Canadian education system, young adult novels, Renaissance palaces). This would allow the reader to fully understand each topic before the comparative analysis is presented.

Using the Point-by-Point Method might be best used with these topics:

• Comparing the use of symbolism in Ernest Hemingway’s “The Old Man and the Sea” and F. Scott Fitzgerald’s “The Great Gatsby.”
• Contrasting the political ideologies of Abraham Lincoln and Theodore Roosevelt
• Analyzing the similarities and differences in the marketing strategies of Coca-Cola and Pepsi

In a point-by-point comparative essay, the writer would alternate between the two subjects in each paragraph, directly comparing and contrasting specific elements (e.g., how symbolism is used, political views, and marketing tactics). This would encourage a more integrated analysis of the similarities and differences between the subjects.

How Can You Brainstorm for a Comparative Essay?

To begin brainstorming for a comparative essay, start by creating a Venn diagram to visually organize the similarities and differences between your chosen topics. This can help you identify key points of comparison and contrast, which will form the foundation of your essay. 

Additionally, consider writing down any questions or observations that arise during this process, as they may guide your subsequent research and analysis.

How Should You Formulate a Thesis Statement for a Comparative Essay?

A thesis statement is a one- or two-sentence summary that conveys a comparative essay’s main argument, focus, or purpose. It provides the reader with an overview of the essay’s central claim, which the rest of the paper will work to develop and support.

Your comparative essay’s thesis statement should clearly explain the central argument or insight that your analysis will explore. This statement should go beyond simply identifying the subjects being compared and instead make a substantive claim about the relationship between them. A strong comparative essay thesis will establish the basis for your comparative analysis and provide a roadmap for the rest of your essay.

For example, using the examples mentioned above, consider these options:

• “Classic literature and modern young adult novels differ greatly in their thematic depth, complexity of characterization, and use of literary devices, though both genres can provide valuable insights into the human experience.”
• “Gothic cathedrals and Renaissance palaces represent vastly contrasting architectural styles, with Gothic structures emphasizing verticality, pointed arches, and religious symbolism, while Renaissance palaces showcase classical proportions, ornate facades, and secular grandeur.”
• “Ernest Hemingway’s ‘The Old Man and the Sea’ and F. Scott Fitzgerald’s ‘The Great Gatsby’ both employ symbolic imagery to explore themes of the human condition, but they do so in strikingly different ways that reflect the author’s distinct writing styles and philosophical perspectives.”
• “Though Abraham Lincoln and Theodore Roosevelt held vastly different political ideologies, with Lincoln championing a strong federal government and Roosevelt advocating for a more progressive, regulatory approach, both presidents played pivotal roles in shaping the course of American history.”

What Strategies Should You Employ When Writing Comparative Essays?

When writing a comparative essay, it’s important to employ various strategies to effectively communicate your analysis. This may include using transition words and phrases to establish connections between ideas, incorporating relevant examples or evidence to support your claims, and maintaining a formal, academic tone throughout your writing. 

Additionally, consider incorporating a Venn diagram or other visual aids to enhance your comparative analysis.

Strategies for Comparative Essays

To recap, use the following strategies in your work to help organize and structure your essay: 

Use Effective Transitions

• Words/phrases like “in contrast,” “on the other hand,” “similarly,” “conversely,” etc.
• Help establish clear connections between ideas and comparisons.

Provide Relevant Examples and Evidence

• Draw from the subjects being compared to support your claims
• Use specific details, quotes, or data to strengthen your analysis

Maintain a Formal, Academic Tone

• Avoid casual or conversational language
• Focus on objective, analytical writing

Incorporate Visual Aids (if appropriate)

• Venn diagrams, tables, or other graphics can effectively illustrate comparisons
• Help the reader visualize the relationships between the subjects

Structure Logically

• Use either the block method or point-by-point organization
• Ensure a clear, coherent flow of ideas

Address Counterarguments or Limitations

• Acknowledge and respond to potential objections or alternative perspectives.
• Demonstrates depth of understanding

Which Mistakes Should You Be Careful of in Comparative Essay Writing?

Here are some examples to illustrate the common mistakes to avoid when writing comparative essays:

Failing to establish a clear basis for comparison

• Attempting to compare the plot of a novel to the musical score of an opera without explaining the relevance of that comparison
• Contrasting two political ideologies without defining the key criteria being used to evaluate them

Neglecting to address significant differences or similarities

• Comparing the leadership styles of two presidents but failing to discuss their differing approaches to domestic or foreign policy
• Analyzing the architectural features of Gothic cathedrals and Renaissance palaces without acknowledging their shared use of symmetry and classical proportions

Providing a superficial or unbalanced analysis

• Dedicating a single paragraph to analyzing the complex socioeconomic factors that shaped the development of two education systems
• The majority of the essay focused on the differences between the two subjects while only briefly mentioning their similarities.

Relying too heavily on plot summary or description

• Retelling the narratives of two novels in detail without delving into a comparative analysis of their themes, character development, or stylistic elements
• Extensively describing the physical attributes of two historical buildings without explaining how those features reflect the broader architectural movements.

Lacking a cohesive and logical organizational structure

• Jumping back and forth between discussing the two subjects without a clear basis for the order or flow of ideas
• Using the block method but failing to create a smooth transition between the sections devoted to each subject

Incorporating specific, relevant examples for each of these potential pitfalls can help illustrate the importance of avoiding them in comparative essay writing. These tips can help you when you just wish you could ask something to “ write my essay for me .”

Why is Revising Your Comparative Essay Crucial?

Revising your comparative essay is always considered an important step in the writing process, as it allows you to refine your analysis, strengthen your arguments, and ensure the overall explanation of connections and effectiveness of your essay. 

During the revision stage, consider seeking feedback from peers or instructors. Their perspectives can help you identify areas for improvement and enhance the quality of your comparative essay.

Reasons to Revise Comparative Essays

Refine Your Analysis

• Example: Upon revision, you realize your comparison of two political ideologies lacks nuance and fails to acknowledge the complexities within each position. You then expand your analysis to provide a more nuanced and balanced perspective.

Strengthen Your Arguments

• Example: During revision, you identify gaps in your supporting evidence for a key point contrasting the marketing strategies of two rival companies. You then incorporate additional data and examples to bolster your comparative claims.

Ensure Coherence and Organization

• Example: In reviewing your essay, you recognize that your use of the point-by-point method is causing your comparisons to feel disjointed. You then reorganize your essay to follow a more cohesive block structure, improving the overall flow of ideas.

Incorporate Peer/Instructor Feedback

• Example: After receiving feedback from your instructor, you realize your comparison of two literary works does not adequately address a significant thematic similarity. You then revise the essay to incorporate this overlooked element into your analysis.

Enhance the Overall Quality

• Example: During the revision process, you identify opportunities to improve the clarity and precision of your language, ensuring your comparative essay communicates your insights effectively to the reader.

A comparative essay is a valuable academic writing exercise that encourages critical thinking, in-depth analysis, and the development of essential written communication skills. By mastering the structure, thesis formulation, and writing strategies associated with comparative essays, students can enhance their ability to engage in thoughtful, well-reasoned comparisons and effectively convey their research, discoveries, and opinions to their audience.

The purpose of a compare and contrast essay is to analyze the differences and/or the similarities of two distinct subjects. A good compare/contrast essay doesn’t only point out how the subjects are similar or different (or even both!). It uses those points to make a meaningful argument about the subjects. While it can be a little intimidating to approach this type of essay at first, with a little work and practice, you can write a great compare-and-contrast essay!

Formulating Your Argument

• You could pick two subjects that are in the same “category” but have differences that are significant in some way. For example, you could choose “homemade pizza vs. frozen grocery store pizza.”
• You could pick two subjects that don’t appear to have anything in common but that have a surprising similarity. For example, you could choose to compare bats and whales. (One is tiny and flies, and the other is huge and swims, but they both use sonar to hunt.)
• You could pick two subjects that might appear to be the same but are actually different. For example, you could choose "The Hunger Games movie vs. the book."

• For example, ask yourself: What can we learn by thinking about “The Hunger Games” and “Battle Royale” together that we would miss out on if we thought about them separately?
• It can be helpful to consider the “So what?” question when deciding whether your subjects have meaningful comparisons and contrasts to be made. If you say “The Hunger Games and Battle Royale are both similar and different,” and your friend asked you “So what?” what would your answer be? In other words, why bother putting these two things together?

• A “Venn diagram” can often be helpful when brainstorming. This set of overlapping circles can help you visualize where your subjects are similar and where they differ. In the outer edges of the circle, you write what is different; in the overlapping middle area, you write what’s similar. [2] X Trustworthy Source University of North Carolina Writing Center UNC's on-campus and online instructional service that provides assistance to students, faculty, and others during the writing process Go to source
• You can also just draw out a list of all of the qualities or characteristics of each subject. Once you’ve done that, start looking through the list for traits that both subjects share. Major points of difference are also good to note.

• For example, if you are comparing and contrasting cats and dogs, you might notice that both are common household pets, fairly easy to adopt, and don’t usually have many special care needs. These are points of comparison (ways they are similar).
• You might also note that cats are usually more independent than dogs, that dogs may not provoke allergies as much as cats do, and that cats don’t get as big as many dogs do. These are points of contrast (ways they are different).
• These points of contrast can often be good places to start thinking about your thesis, or argument. Do these differences make one animal a superior type of pet? Or a better pet choice for a specific living situation (e.g., an apartment, a farm, etc.)?

• Show readers why one subject is more desirable than the other. Example: "Cats are better pets than dogs because they require less maintenance, are more independent, and are more adaptable."
• Help readers make a meaningful comparison between two subjects. Example: "New York City and San Francisco are both great cities for young professionals, but they differ in terms of their job opportunities, social environment, and living conditions."
• Show readers how two subjects are similar and different. Example: "While both The Catcher in the Rye and To Kill a Mockingbird explore the themes of loss of innocence and the deep bond between siblings, To Kill a Mockingbird is more concerned with racism while The Catcher in the Rye focuses on the prejudices of class."
• In middle school and high school, the standard format for essays is often the “5-paragraph form,” with an introduction, 3 body paragraphs, and a conclusion. If your teacher recommends this form, go for it. However, you should be aware that especially in college, teachers and professors tend to want students to break out of this limited mode. Don’t get so locked into having “three main points” that you forget to fully explore your topic.

Organizing Your Essay

• Subject by subject. This organization deals with all of the points about Topic A, then all of the points of Topic B. For example, you could discuss all your points about frozen pizza (in as many paragraphs as necessary), then all your points about homemade pizza. The strength of this form is that you don’t jump back and forth as much between topics, which can help your essay read more smoothly. It can also be helpful if you are using one subject as a “lens” through which to examine the other. The major disadvantage is that the comparisons and contrasts don’t really become evident until much further into the essay, and it can end up reading like a list of “points” rather than a cohesive essay. [4] X Trustworthy Source University of North Carolina Writing Center UNC's on-campus and online instructional service that provides assistance to students, faculty, and others during the writing process Go to source
• Point by point. This type of organization switches back and forth between points. For example, you could first discuss the prices of frozen pizza vs. homemade pizza, then the quality of ingredients, then the convenience factor. The advantage of this form is that it’s very clear what you’re comparing and contrasting. The disadvantage is that you do switch back and forth between topics, so you need to make sure that you use transitions and signposts to lead your reader through your argument.
• Compare then contrast. This organization presents all the comparisons first, then all the contrasts. It’s a pretty common way of organizing an essay, and it can be helpful if you really want to emphasize how your subjects are different. Putting the contrasts last places the emphasis on them. However, it can be more difficult for your readers to immediately see why these two subjects are being contrasted if all the similarities are first.

• Introduction. This paragraph comes first and presents the basic information about the subjects to be compared and contrasted. It should present your thesis and the direction of your essay (i.e., what you will discuss and why your readers should care).
• Body Paragraphs. These are the meat of your essay, where you provide the details and evidence that support your claims. Each different section or body paragraph should tackle a different division of proof. It should provide and analyze evidence in order to connect those proofs to your thesis and support your thesis. Many middle-school and high-school essays may only require three body paragraphs, but use as many as is necessary to fully convey your argument.
• Acknowledgement of Competitive Arguments/Concession. This paragraph acknowledges that other counter-arguments exist, but discusses how those arguments are flawed or do not apply.
• Conclusion. This paragraph summarizes the evidence presented. It will restate the thesis, but usually in a way that offers more information or sophistication than the introduction could. Remember: your audience now has all the information you gave them about why your argument is solid. They don’t need you to just reword your original thesis. Take it to the next level!

• Introduction: state your intent to discuss the differences between camping in the woods or on the beach.
• Body Paragraph 1 (Woods): Climate/Weather
• Body Paragraph 2 (Woods): Types of Activities and Facilities
• Body Paragraph 3 (Beach): Climate/Weather
• Body Paragraph 4 (Beach): Types of Activities and Facilities

• Introduction

• Body Paragraph 1: Similarity between woods and beaches (both are places with a wide variety of things to do)
• Body Paragraph 2: First difference between woods and beaches (they have different climates)
• Body Paragraph 3: Second difference between woods and beaches (there are more easily accessible woods than beaches in most parts of the country)
• Body Paragraph 4: Emphasis on the superiority of the woods to the beach

• Topic sentence: This sentence introduces the main idea and subject of the paragraph. It can also provide a transition from the ideas in the previous paragraph.
• Body: These sentences provide concrete evidence that support the topic sentence and main idea.
• Conclusion: this sentence wraps up the ideas in the paragraph. It may also provide a link to the next paragraph’s ideas.

Putting It All Together

• If you are having trouble finding evidence to support your argument, go back to your original texts and try the brainstorming process again. It could be that your argument is evolving past where it started, which is good! You just need to go back and look for further evidence.

• For example, in a body paragraph about the quality of ingredients in frozen vs. homemade pizza, you could close with an assertion like this: “Because you actively control the quality of the ingredients in pizza you make at home, it can be healthier for you than frozen pizza. It can also let you express your imagination. Pineapple and peanut butter pizza? Go for it! Pickles and parmesan? Do it! Using your own ingredients lets you have fun with your food.” This type of comment helps your reader understand why the ability to choose your own ingredients makes homemade pizza better.

• Reading your essay aloud can also help you find problem spots. Often, when you’re writing you get so used to what you meant to say that you don’t read what you actually said.

• Avoid bias. Don't use overly negative or defamatory language to show why a subject is unfavorable; use solid evidence to prove your points instead.
• Avoid first-person pronouns unless told otherwise. In some cases, your teacher may encourage you to use “I” and “you” in your essay. However, if the assignment or your teacher doesn’t mention it, stick with third-person instead, like “one may see” or “people may enjoy.” This is common practice for formal academic essays.
• Proofread! Spelling and punctuation errors happen to everyone, but not catching them can make you seem lazy. Go over your essay carefully, and ask a friend to help if you’re not confident in your own proofreading skills.

Sample Body Paragraphs

• "When one is deciding whether to go to the beach or the woods, the type of activities that each location offers are an important point to consider. At the beach, one can enjoy the water by swimming, surfing, or even building a sandcastle with a moat that will fill with water. When one is in the woods, one may be able to go fishing or swimming in a nearby lake, or one may not be near water at all. At the beach, one can keep one's kids entertained by burying them in sand or kicking around a soccer ball; if one is in the woods, one can entertain one's kids by showing them different plans or animals. Both the beach and the woods offer a variety of activities for adults and kids alike."

• "The beach has a wonderful climate, many activities, and great facilities for any visitor's everyday use. If a person goes to the beach during the right day or time of year, he or she can enjoy warm, yet refreshing water, a cool breeze, and a relatively hot climate. At the beach, one can go swimming, sunbathe, or build sandcastles. There are also great facilities at the beach, such as a changing room, umbrellas, and conveniently-located restaurants and changing facilities. The climate, activities, and facilities are important points to consider when deciding between the beach and the woods."

Comparing and Contrasting

What this handout is about.

This handout will help you first to determine whether a particular assignment is asking for comparison/contrast and then to generate a list of similarities and differences, decide which similarities and differences to focus on, and organize your paper so that it will be clear and effective. It will also explain how you can (and why you should) develop a thesis that goes beyond “Thing A and Thing B are similar in many ways but different in others.”

Introduction

In your career as a student, you’ll encounter many different kinds of writing assignments, each with its own requirements. One of the most common is the comparison/contrast essay, in which you focus on the ways in which certain things or ideas—usually two of them—are similar to (this is the comparison) and/or different from (this is the contrast) one another. By assigning such essays, your instructors are encouraging you to make connections between texts or ideas, engage in critical thinking, and go beyond mere description or summary to generate interesting analysis: when you reflect on similarities and differences, you gain a deeper understanding of the items you are comparing, their relationship to each other, and what is most important about them.

Recognizing comparison/contrast in assignments

Some assignments use words—like compare, contrast, similarities, and differences—that make it easy for you to see that they are asking you to compare and/or contrast. Here are a few hypothetical examples:

• Compare and contrast Frye’s and Bartky’s accounts of oppression.
• Compare WWI to WWII, identifying similarities in the causes, development, and outcomes of the wars.
• Contrast Wordsworth and Coleridge; what are the major differences in their poetry?

Notice that some topics ask only for comparison, others only for contrast, and others for both.

But it’s not always so easy to tell whether an assignment is asking you to include comparison/contrast. And in some cases, comparison/contrast is only part of the essay—you begin by comparing and/or contrasting two or more things and then use what you’ve learned to construct an argument or evaluation. Consider these examples, noticing the language that is used to ask for the comparison/contrast and whether the comparison/contrast is only one part of a larger assignment:

• Choose a particular idea or theme, such as romantic love, death, or nature, and consider how it is treated in two Romantic poems.
• How do the different authors we have studied so far define and describe oppression?
• Compare Frye’s and Bartky’s accounts of oppression. What does each imply about women’s collusion in their own oppression? Which is more accurate?
• In the texts we’ve studied, soldiers who served in different wars offer differing accounts of their experiences and feelings both during and after the fighting. What commonalities are there in these accounts? What factors do you think are responsible for their differences?

You may want to check out our handout on understanding assignments for additional tips.

Using comparison/contrast for all kinds of writing projects

Sometimes you may want to use comparison/contrast techniques in your own pre-writing work to get ideas that you can later use for an argument, even if comparison/contrast isn’t an official requirement for the paper you’re writing. For example, if you wanted to argue that Frye’s account of oppression is better than both de Beauvoir’s and Bartky’s, comparing and contrasting the main arguments of those three authors might help you construct your evaluation—even though the topic may not have asked for comparison/contrast and the lists of similarities and differences you generate may not appear anywhere in the final draft of your paper.

Discovering similarities and differences

Making a Venn diagram or a chart can help you quickly and efficiently compare and contrast two or more things or ideas. To make a Venn diagram, simply draw some overlapping circles, one circle for each item you’re considering. In the central area where they overlap, list the traits the two items have in common. Assign each one of the areas that doesn’t overlap; in those areas, you can list the traits that make the things different. Here’s a very simple example, using two pizza places:

To make a chart, figure out what criteria you want to focus on in comparing the items. Along the left side of the page, list each of the criteria. Across the top, list the names of the items. You should then have a box per item for each criterion; you can fill the boxes in and then survey what you’ve discovered.

Here’s an example, this time using three pizza places:

As you generate points of comparison, consider the purpose and content of the assignment and the focus of the class. What do you think the professor wants you to learn by doing this comparison/contrast? How does it fit with what you have been studying so far and with the other assignments in the course? Are there any clues about what to focus on in the assignment itself?

Here are some general questions about different types of things you might have to compare. These are by no means complete or definitive lists; they’re just here to give you some ideas—you can generate your own questions for these and other types of comparison. You may want to begin by using the questions reporters traditionally ask: Who? What? Where? When? Why? How? If you’re talking about objects, you might also consider general properties like size, shape, color, sound, weight, taste, texture, smell, number, duration, and location.

Two historical periods or events

• When did they occur—do you know the date(s) and duration? What happened or changed during each? Why are they significant?
• What kinds of work did people do? What kinds of relationships did they have? What did they value?
• What kinds of governments were there? Who were important people involved?
• What caused events in these periods, and what consequences did they have later on?

Two ideas or theories

• What are they about?
• Did they originate at some particular time?
• Who created them? Who uses or defends them?
• What is the central focus, claim, or goal of each? What conclusions do they offer?
• How are they applied to situations/people/things/etc.?
• Which seems more plausible to you, and why? How broad is their scope?
• What kind of evidence is usually offered for them?

Two pieces of writing or art

• What are their titles? What do they describe or depict?
• What is their tone or mood? What is their form?
• Who created them? When were they created? Why do you think they were created as they were? What themes do they address?
• Do you think one is of higher quality or greater merit than the other(s)—and if so, why?
• For writing: what plot, characterization, setting, theme, tone, and type of narration are used?
• Where are they from? How old are they? What is the gender, race, class, etc. of each?
• What, if anything, are they known for? Do they have any relationship to each other?
• What are they like? What did/do they do? What do they believe? Why are they interesting?
• What stands out most about each of them?

Deciding what to focus on

By now you have probably generated a huge list of similarities and differences—congratulations! Next you must decide which of them are interesting, important, and relevant enough to be included in your paper. Ask yourself these questions:

• What’s relevant to the assignment?
• What’s relevant to the course?
• What’s interesting and informative?
• What matters to the argument you are going to make?
• What’s basic or central (and needs to be mentioned even if obvious)?
• Overall, what’s more important—the similarities or the differences?

Suppose that you are writing a paper comparing two novels. For most literature classes, the fact that they both use Caslon type (a kind of typeface, like the fonts you may use in your writing) is not going to be relevant, nor is the fact that one of them has a few illustrations and the other has none; literature classes are more likely to focus on subjects like characterization, plot, setting, the writer’s style and intentions, language, central themes, and so forth. However, if you were writing a paper for a class on typesetting or on how illustrations are used to enhance novels, the typeface and presence or absence of illustrations might be absolutely critical to include in your final paper.

Sometimes a particular point of comparison or contrast might be relevant but not terribly revealing or interesting. For example, if you are writing a paper about Wordsworth’s “Tintern Abbey” and Coleridge’s “Frost at Midnight,” pointing out that they both have nature as a central theme is relevant (comparisons of poetry often talk about themes) but not terribly interesting; your class has probably already had many discussions about the Romantic poets’ fondness for nature. Talking about the different ways nature is depicted or the different aspects of nature that are emphasized might be more interesting and show a more sophisticated understanding of the poems.

Your thesis

The thesis of your comparison/contrast paper is very important: it can help you create a focused argument and give your reader a road map so they don’t get lost in the sea of points you are about to make. As in any paper, you will want to replace vague reports of your general topic (for example, “This paper will compare and contrast two pizza places,” or “Pepper’s and Amante are similar in some ways and different in others,” or “Pepper’s and Amante are similar in many ways, but they have one major difference”) with something more detailed and specific. For example, you might say, “Pepper’s and Amante have similar prices and ingredients, but their atmospheres and willingness to deliver set them apart.”

Be careful, though—although this thesis is fairly specific and does propose a simple argument (that atmosphere and delivery make the two pizza places different), your instructor will often be looking for a bit more analysis. In this case, the obvious question is “So what? Why should anyone care that Pepper’s and Amante are different in this way?” One might also wonder why the writer chose those two particular pizza places to compare—why not Papa John’s, Dominos, or Pizza Hut? Again, thinking about the context the class provides may help you answer such questions and make a stronger argument. Here’s a revision of the thesis mentioned earlier:

Pepper’s and Amante both offer a greater variety of ingredients than other Chapel Hill/Carrboro pizza places (and than any of the national chains), but the funky, lively atmosphere at Pepper’s makes it a better place to give visiting friends and family a taste of local culture.

Organizing your paper

There are many different ways to organize a comparison/contrast essay. Here are two:

Subject-by-subject

Begin by saying everything you have to say about the first subject you are discussing, then move on and make all the points you want to make about the second subject (and after that, the third, and so on, if you’re comparing/contrasting more than two things). If the paper is short, you might be able to fit all of your points about each item into a single paragraph, but it’s more likely that you’d have several paragraphs per item. Using our pizza place comparison/contrast as an example, after the introduction, you might have a paragraph about the ingredients available at Pepper’s, a paragraph about its location, and a paragraph about its ambience. Then you’d have three similar paragraphs about Amante, followed by your conclusion.

The danger of this subject-by-subject organization is that your paper will simply be a list of points: a certain number of points (in my example, three) about one subject, then a certain number of points about another. This is usually not what college instructors are looking for in a paper—generally they want you to compare or contrast two or more things very directly, rather than just listing the traits the things have and leaving it up to the reader to reflect on how those traits are similar or different and why those similarities or differences matter. Thus, if you use the subject-by-subject form, you will probably want to have a very strong, analytical thesis and at least one body paragraph that ties all of your different points together.

A subject-by-subject structure can be a logical choice if you are writing what is sometimes called a “lens” comparison, in which you use one subject or item (which isn’t really your main topic) to better understand another item (which is). For example, you might be asked to compare a poem you’ve already covered thoroughly in class with one you are reading on your own. It might make sense to give a brief summary of your main ideas about the first poem (this would be your first subject, the “lens”), and then spend most of your paper discussing how those points are similar to or different from your ideas about the second.

Point-by-point

Rather than addressing things one subject at a time, you may wish to talk about one point of comparison at a time. There are two main ways this might play out, depending on how much you have to say about each of the things you are comparing. If you have just a little, you might, in a single paragraph, discuss how a certain point of comparison/contrast relates to all the items you are discussing. For example, I might describe, in one paragraph, what the prices are like at both Pepper’s and Amante; in the next paragraph, I might compare the ingredients available; in a third, I might contrast the atmospheres of the two restaurants.

If I had a bit more to say about the items I was comparing/contrasting, I might devote a whole paragraph to how each point relates to each item. For example, I might have a whole paragraph about the clientele at Pepper’s, followed by a whole paragraph about the clientele at Amante; then I would move on and do two more paragraphs discussing my next point of comparison/contrast—like the ingredients available at each restaurant.

There are no hard and fast rules about organizing a comparison/contrast paper, of course. Just be sure that your reader can easily tell what’s going on! Be aware, too, of the placement of your different points. If you are writing a comparison/contrast in service of an argument, keep in mind that the last point you make is the one you are leaving your reader with. For example, if I am trying to argue that Amante is better than Pepper’s, I should end with a contrast that leaves Amante sounding good, rather than with a point of comparison that I have to admit makes Pepper’s look better. If you’ve decided that the differences between the items you’re comparing/contrasting are most important, you’ll want to end with the differences—and vice versa, if the similarities seem most important to you.

Our handout on organization can help you write good topic sentences and transitions and make sure that you have a good overall structure in place for your paper.

Cue words and other tips

To help your reader keep track of where you are in the comparison/contrast, you’ll want to be sure that your transitions and topic sentences are especially strong. Your thesis should already have given the reader an idea of the points you’ll be making and the organization you’ll be using, but you can help them out with some extra cues. The following words may be helpful to you in signaling your intentions:

• like, similar to, also, unlike, similarly, in the same way, likewise, again, compared to, in contrast, in like manner, contrasted with, on the contrary, however, although, yet, even though, still, but, nevertheless, conversely, at the same time, regardless, despite, while, on the one hand … on the other hand.

For example, you might have a topic sentence like one of these:

• Compared to Pepper’s, Amante is quiet.
• Like Amante, Pepper’s offers fresh garlic as a topping.
• Despite their different locations (downtown Chapel Hill and downtown Carrboro), Pepper’s and Amante are both fairly easy to get to.
