How to Write a Synthesis Essay Conclusion

November 2, 2022 by Beth Hall

If you’re taking the AP ® Lang exam, you might be wondering if a synthesis essay conclusion is even necessary. You also might be wondering how to write a synthesis essay conclusion. The answer to the first question is it depends. Keep reading to find out why.

Priorities When Writing a Synthesis Essay Conclusion

Before you even attempt to write a conclusion for synthesis essays, it is crucial to make sure you do other aspects first. This is because the conclusion is not necessary. Simply put, it is not part of the rubric. Think of your exam essay more as a rough draft, and sometimes we do not get time to write the conclusion at this point. That’s okay! You are under a lot of stress, so the priority needs to be on the aspects within the rubric, especially the evidence and commentary in your body paragraphs.

Before attempting the synthesis essay conclusion, be sure you’ve clearly cited 3 of the provided sources. This is the only way to score within the higher numbers for the evidence and commentary row. For more guidance on writing the body of the synthesis essay, be sure to read How to Write a Synthesis Essay. This blog post outlines the entire writing process to help you earn the best score possible. 

Additionally, you want to be sure that you have well-developed body paragraphs. If you have to choose between writing more in your body paragraphs or writing a conclusion, typically, it will be helpful to focus on the body paragraphs. This is because your body paragraphs contain evidence and commentary, which are 4 of the possible 6 points on the rubric.

To Write or Not To Write a Synthesis Essay Conclusion?

After finishing the body paragraphs, you want to check the remaining time. Ask yourself: Do I have enough time to write a conclusion? If you have at least three sources and your body paragraphs are strong, it is time to begin the conclusion. 

When writing a conclusion paragraph for synthesis essays, some students will restate the thesis. This is fine–just make sure you don’t copy it verbatim. Others might worry that the original thesis was not defensible and want to have a stronger conclusion. This means they come up with a stronger thesis as they conclude the essay. 

Developing Your Synthesis Conclusion

When working on your synthesis essay conclusion, you may want to develop your conclusion beyond just restating your thesis. Here are some questions to consider to help you develop your synthesis essay conclusion paragraph: 

  • Who is helped or harmed by the issue? In other words, who benefits and who is at a disadvantage?
  • What are the short-term and long-term societal implications of this issue?
  • Why does this issue really matter?
  • Why is this issue relevant on a local, national, or even international level? For this question, you do not have to answer all parts. Which level to focus on depends on the topic itself. 
  • Do you have any outside knowledge you could connect to the issue to show why it is essential? 
  • How does the issue connect to the future? For example, you can even include personal experience to help show why the topic matters. Then, you can include why this topic is important to the future. 

Answering any of these questions within the conclusion of the synthesis essay helps you offer deeper insight, possibly situation the issue in a broader context. 

Another possible way to end your synthesis essay conclusion is a call to action. This is when you challenge your audience to go and do something. You want to encourage people to act. This may be the reader, or it may be parents, educators, politicians, and businesses. However, it is important to remember this is not appropriate for every essay and prompt. It is a tool to have in your toolbox in case it works for the prompt on exam day. You want to use it sparingly and thoughtfully. 

If applicable, you can also make note relevant personal experience or observations in your conclusion to help address why this issue or topic matters in the real-world, beyond what the provided sources say.

Writing the Conclusion 

When learning how to write a synthesis essay conclusion, it is important to avoid the phrases “in conclusion,” “all in all,” or “to sum it up.” Those are a little bit too simple.  When leading into the conclusion paragraph, I recommend something like “When considering…” and then going into the topic. After, incorporate something like “It becomes clear/apparent/evident that…” and re-elaborate on your stance. Then, wrap everything up with strong concluding words, such as “Therefore” or “Thus.” As you write, remember it is okay to use language from the prompt! 

When it comes time to write the synthesis essay, focus on the body paragraphs and sources. You are graded against a rubric, so you want to give yourself the best chance at a high score. However, you also want to know how to write a synthesis essay conclusion. While this is not a requirement, it is a great way to create a solid ending to your essay should you have the time.

10 effective strategies for writing a successful synthesis essay that will impress your readers.

How to write a synthesis essay

In the realm of written expression, the fusion of ideas from various sources has long been regarded as one of the most intellectually stimulating endeavors. Being able to synthesize information from disparate fields of knowledge not only demonstrates a profound understanding of the subject matter, but also enables the author to introduce novel insights and perspectives. A synthesis essay, as its name suggests, requires a writer to assimilate and integrate ideas, arguments, and evidence from multiple sources into a cohesive and compelling piece of writing. This type of essay invites writers to harness their analytical skills and creative thinking abilities to produce a work that advances a unique and persuasive viewpoint.

Central to the craft of writing a synthesis essay is the utilization of synthesis techniques, which allow the author to achieve the desired integration of ideas. By employing these techniques, such as comparison and contrast, analysis and evaluation, and critique and synthesis, the writer can effectively merge ideas from different sources in a clear and coherent manner. Through the skillful application of these techniques, the writer can establish connections, draw parallels, and highlight the interrelationships of ideas, thereby creating a nuanced and sophisticated argument.

Examples serve as valuable tools in illustrating the principles and techniques of crafting a successful synthesis essay. For instance, consider a synthesis essay on the topic of climate change. In this essay, the writer integrates scientific research papers, political speeches, and personal testimony to create a comprehensive and persuasive argument for the urgent need for global action on climate change. By skillfully weaving together these diverse sources, the writer is able to present a multi-dimensional perspective on the issue while maintaining a clear and compelling narrative.

Step 7: Write the Conclusion

Step 9: Proofread and Polish

Before submitting your final essay, proofread it one last time to catch any lingering errors. Pay attention to spelling, grammar, and punctuation mistakes. Additionally, ensure that your formatting and citations are consistent throughout the essay.

Understanding the Purpose of a Synthesis Essay

Exploring the Rationale Behind Composing a Synthesis Paper

A synthesis essay is a unique form of academic writing that requires students to combine information from multiple sources to support a thesis statement. In this type of essay, the writer needs to analyze various perspectives and synthesize them into a coherent argument. The purpose of a synthesis essay is to demonstrate a deep understanding of a topic by presenting a well-structured and balanced synthesis of different viewpoints or approaches.

When writing a synthesis essay, it is essential to understand the purpose behind this type of assignment. The primary goal is not merely to summarize the information from the sources but to present an original perspective that emerges from the synthesis of these sources. By carefully analyzing and evaluating the information from various sources, students can develop a unique understanding of the topic and present their own insights.

Moreover, a synthesis essay allows students to demonstrate critical thinking and analytical skills. It requires them to evaluate the credibility and relevance of the sources used and to consider how different ideas and perspectives relate to one another. By carefully selecting and integrating information from diverse sources, students can create a cohesive argument that goes beyond a mere summary of the sources.

Another important purpose of a synthesis essay is to foster effective communication and persuasive writing skills. Through the synthesis process, students learn how to effectively convey their ideas and support them with evidence from the sources. They need to consider the audience and tailor their argument to appeal to the readers. By organizing their thoughts and ideas in a logical and coherent manner, students can make a persuasive case for their thesis statement.

In summary, the purpose of a synthesis essay is to demonstrate a deep understanding of a topic by synthesizing information from multiple sources into a cohesive argument. It requires students to analyze and evaluate various viewpoints and to develop their own unique perspective. Additionally, a synthesis essay cultivates critical thinking skills and effective communication abilities. By mastering the art of synthesis writing, students can become more proficient in academic research and persuasive writing, making their essays more compelling and insightful.

Choosing a Relevant Topic for Your Synthesis Essay

Choosing a Relevant Topic for Your Synthesis Essay

When embarking on a journey of writing a synthesis essay, one of the most crucial steps is selecting a pertinent topic that encompasses the essence of your discussion. This stage requires careful consideration and evaluation in order to ensure that you have a solid foundation on which to build your argument.

To begin, it is essential to understand that a relevant topic should address the central theme or question that you are exploring in your synthesis essay. It should encapsulate the diverse perspectives and ideas that you aim to synthesize in your composition. By choosing a topic that is pertinent to your thesis statement, you can create a cohesive and persuasive argument.

When selecting a topic, it is important to choose something that is not only interesting to you but also holds relevance to the current context. Consider the current societal issues, scientific advancements, or technological developments that are shaping the world around us. By delving into a topic that is timely and impactful, you can engage your readers and make your synthesis essay more compelling.

Furthermore, it is crucial to choose a topic that allows for a variety of sources and perspectives to be integrated into your essay. Look for subjects that have a wealth of research materials available from reputable sources such as academic journals, books, and established experts in the field. This will provide you with a diverse range of perspectives to consider and synthesize in your argument.

In conclusion, choosing a relevant topic for your synthesis essay is a critical step in the writing process. By selecting a topic that aligns with your thesis statement, holds relevance in the current context, and allows for a variety of perspectives to be included, you can create a well-rounded and persuasive synthesis essay that effectively conveys your argument.

Gathering and Evaluating Sources for Your Essay

When embarking on writing a synthesis essay, it is crucial to gather and evaluate reliable sources to support your arguments effectively. A successful essay depends on the quality and relevance of the sources you include. This section will provide you with some valuable tips on how to gather and evaluate sources for your essay.

1. Determine the scope of your essay: Before you start collecting sources, it is important to have a clear understanding of the scope and topic of your essay. This will help you narrow down your search and choose sources that are most relevant to your argument.

2. Use a variety of sources: In order to provide a well-rounded view on the topic, it is recommended to include a mix of primary and secondary sources. Primary sources can include original research studies, interviews, or firsthand accounts, while secondary sources can be scholarly articles, books, or reputable websites that analyze and interpret the primary sources.

3. Evaluate the credibility of the sources: It is essential to evaluate the credibility and reliability of the sources you find. Consider the author’s credentials, the reputation of the publication or website, and whether the information has been peer-reviewed or fact-checked. Avoid relying heavily on sources that lack authority or have a bias.

4. Check for currency: Ensure that the sources you choose are up to date and reflect the most current research and information on the topic. This is particularly important if you are writing about a rapidly evolving field or a current issue.

5. Take notes and keep track of your sources: As you gather your sources, it is crucial to take detailed notes and keep track of the bibliographic information. This will make it easier to properly credit your sources and create an accurate bibliography later on.

6. Consider diverse perspectives: While it can be tempting to rely on sources that align with your own views, it is important to consider diverse perspectives. Including sources with differing opinions can strengthen your argument and demonstrate that you have considered multiple viewpoints.

By following these tips and gathering a range of reliable sources, you will be well-equipped to write a compelling synthesis essay that is backed by solid evidence and argumentation.

Developing a Thesis Statement for Your Synthesis Essay

In the process of writing a synthesis essay, one of the most crucial steps is developing a strong thesis statement. A thesis statement sets the tone and direction for your essay, guiding the reader on what to expect and how the different sources you will be synthesizing contribute to your overall argument.

When developing a thesis statement for your synthesis essay, it is important to consider the main idea you want to convey and the point you want to make. Your thesis statement should be clear, concise, and specific, providing a roadmap for your essay and outlining the main arguments you will be making.

One approach to developing a thesis statement is to carefully analyze the sources you will be synthesizing and identify common themes or patterns. Look for similarities and differences among the sources and identify the main ideas that emerge. Your thesis statement can then highlight these main ideas and showcase how they intersect and contribute to your overall argument.

Another approach to developing a thesis statement is to consider the main arguments or perspectives presented in the sources and craft a statement that expresses your position on the topic. Your thesis statement can be a synthesis of these different perspectives, presenting a nuanced and balanced argument that incorporates multiple viewpoints.

Remember, a strong thesis statement is essential for a successful synthesis essay. It provides a clear roadmap for your essay and allows your reader to understand the main arguments you will be making. Take the time to carefully craft your thesis statement, ensuring it is specific, concise, and reflective of the main ideas you will be exploring in your essay.

Structuring Your Synthesis Essay for Effective Organization

Creating a well-structured synthesis essay is crucial for effective organization and a clear presentation of your ideas. A strong structure allows your readers to easily follow your argument and understand the connections between different sources and viewpoints. In this section, we will explore some key strategies for structuring your synthesis essay to ensure a cohesive and persuasive piece of writing.

1. Introduction: Start your essay with a compelling introduction that grabs your reader’s attention and clearly presents the topic you will be discussing. Provide some background information on the issue, highlight its significance, and state your thesis statement, which will guide your argument throughout the essay.

2. Body paragraphs: Divide your essay into several body paragraphs, each addressing a specific aspect of your topic. Begin each paragraph with a topic sentence that introduces the main idea or argument you will be discussing. Support your points with evidence from your sources, making sure to cite them properly. Use transitions between paragraphs and within sentences to create a smooth flow of ideas and to establish connections between different viewpoints.

3. Analysis and synthesis: While presenting the ideas from your sources, make sure to analyze and evaluate them critically. Discuss the strengths and weaknesses of each source, identify any biases or limitations, and consider how they contribute to your overall argument. Aim to synthesize the information from your sources, combining different perspectives to support your own viewpoint.

4. Counterarguments: Address and refute counterarguments to strengthen your argument and demonstrate a thorough understanding of the topic. Anticipate possible objections and provide evidence or reasoning to counter them. Acknowledging opposing viewpoints but explaining why they are flawed further strengthens your own argument and credibility.

5. Conclusion: Wrap up your essay with a strong conclusion that summarizes your main points and restates your thesis in a clear and compelling manner. Avoid introducing new information in the conclusion, but instead, emphasize the significance of your argument and its implications.

By structuring your synthesis essay in an organized and logical manner, you can ensure that your ideas are presented cohesively and persuasively. Remember to revise and edit your essay for clarity, coherence, and grammar, and proofread it carefully before submission. With a well-structured essay, you can effectively convey your argument and convince your readers of your viewpoint.

Writing and Revising Your Synthesis Essay

Crafting and fine-tuning your synthesis essay is an essential step in the writing process. Once you have conducted comprehensive research and gathered a plethora of sources, it’s time to consolidate your findings and present them in a cohesive and persuasive manner.

When it comes to writing your synthesis essay, it is crucial to lay a solid foundation. Begin by organizing your thoughts and ideas into an outline, creating a clear and logical structure for your essay. This framework will serve as a roadmap, guiding you through the writing process and ensuring that your arguments flow smoothly.

Once your outline is complete, you can begin the actual writing process. Start with a strong introduction that captures the reader’s attention and clearly states your thesis statement. From there, proceed to develop your ideas in a series of well-crafted paragraphs, each with its own topic sentence and supporting evidence.

As you write, remember to maintain a formal and academic tone, using appropriate language and avoiding slang or colloquialisms. Your synthesis essay should demonstrate your understanding of the topic and your ability to effectively analyze and synthesize information from a variety of sources.

Once you have completed your initial draft, it is essential to revise and edit your synthesis essay to ensure its clarity and coherence. Begin by reviewing the overall structure and organization of your essay. Check that your paragraphs flow smoothly and logically, and ensure that your thesis statement is well-supported by the evidence presented.

Next, focus on the content of your essay. Review each paragraph to ensure that it contributes to the overall argument and that the evidence presented is relevant and persuasive. Consider whether there are any gaps in your analysis or any areas that could benefit from further development.

In addition to content, pay attention to the style and mechanics of your writing. Check for grammatical and spelling errors, and ensure that your sentences are clear, concise, and varied. Consider the use of appropriate transitions to guide your reader through your essay and help them follow your line of reasoning.

Lastly, take the time to proofread your essay carefully. Read it aloud, or have someone else read it to you, to catch any errors or areas that could be strengthened. Remember, the revision process is an opportunity to refine and improve your essay, so take the time to make necessary changes and ensure that your synthesis is well-crafted and compelling.

How to Write a Synthesis Essay

Matt Ellis

Synthesis essays are common assignments in both high school and university, but that doesn’t mean they’re easy or that everyone knows how to write them. In this guide, we discuss everything you need to know in order to write one yourself. We talk about synthesis essay structure and offer some general tips, plus we clarify any confusion between a synthesis essay versus an argumentative essay.

Cite your sources with confidence Grammarly helps you avoid plagiarism Write with Grammarly

What is a synthesis essay?

A synthesis essay is a type of essay that combines points, data, and evidence from multiple sources and turns them into one idea that the writing revolves around. In other words, the writer synthesizes their own idea using other sources’ research and points. Usually, synthesis essays are a type of analytical essay , but they have crossover with other types of essays as well, such as argumentative essays .

The central idea in a synthesis essay is represented by the thesis statement , a sentence that succinctly explains the main point of the essay. In a synthesis essay, this “new” idea usually consolidates the main points and/or findings of other sources.

Synthesis essay structure

Creating a solid synthesis essay structure is one of the hardest parts of writing a synthesis essay. Unlike most other essay outlines , an outline for a synthesis essay has to include points from multiple sources, and such combinations don’t always have a logical or chronological sequence. To help you out, here are three strategies for creating a synthesis essay structure and sample outlines that you can use as templates.

Synthesis essay structure 1: By topic

The first kind of synthesis essay structure involves discussing each topic individually, mentioning each source’s perspective on it, and then moving on to the next topic. This approach lets you compare or join together points made by different sources about the same specific topic.

Structuring your synthesis essay by topic works best for more complicated ideas with different aspects that should be explored individually.

Example outline:

I. Introduction A. Thesis statement

II. Topic 1 A. Source A discussing Topic 1 1. A point or piece of evidence/data from Source A about Topic 1 2. Another point or piece of evidence/data from Source A about Topic 1 3. [Etc.]

B. Source B discussing Topic 1 1. A point or piece of evidence/data from Source B about Topic 1 2. [Etc.] 

III. Topic 2 A. Source A discussing Topic 2 B. [Etc.] 

IV. Topic 3 A. [Etc.]

[You can keep going like this with as many topics as you need.]

V. Conclusion A. Revisit thesis statement

Synthesis essay structure 2: By source

Alternatively, you can organize your synthesis essay structure by source: You discuss the main points of one source together and then move on to another source. This approach lets you compartmentalize the main points according to where they come from but ultimately bring together the main points from different sources.

Structuring your synthesis essay by source works best when you want to emphasize the sources themselves over the points they make. For example, if you were using this type of structure for an argumentative essay, you might want to fully discuss the source you’re refuting before making your counterargument.

II. Source 1 A. Source 1 discussing Topic A 1. A point or piece of evidence/data from Source 1 about Topic A 2. Another point or piece of evidence/data from Source 1 about Topic A 3. [Etc.]

B. Source 1 discussing Topic B 1. A point or piece of evidence/data from Source 1 about Topic B 2. [Etc.]

III. Source 2 A. Source 2 discussing Topic A B. Source 2 discussing Topic B C. [Etc.]

IV. Source 3 A. [Etc.]

[You can keep going like this for all your sources.]

V. Conclusion 1. Revisit thesis statement

Synthesis essay structure 3: Combine

The synthesis essay structures above are by no means set in stone. You’re free to adapt or modify them however you need and can even combine them.

For example, what if there’s a special source that stands out from the others? You could begin your synthesis essay by discussing each topic individually so that your reader understands the issue. Then you could switch it up and include a section just for that one special source, explaining that source’s stance on the previously discussed topics.

3 tips for writing a synthesis essay

1 come up with a strong thesis statement.

As mentioned above, a thesis statement is a single sentence that briefly explains the main point of your essay. In a synthesis essay, the thesis statement should effectively bring together the ideas and points from multiple other sources.

Part of writing a strong thesis statement comes from choosing your essay topic . Pick a topic that is broad enough to have sufficient research and enough other sources discussing it but specific enough that you can cover everything.

As for writing the actual thesis statement, a helpful method is to phrase your topic as a question and then answer it. The answer could be a good start to your thesis statement sentence. For example, let’s say your topic is how Denmark came to be first in clean energy. You could phrase the question and answer as:

Q: “Why is Denmark the leading country in renewable energy?”

A: “Denmark is first in clean energy thanks in part to energy conservation from district heating, combined heat-and-power stations, and its use of small, locally based power plants instead of larger ones.”

That answer could double as your thesis statement and mentions some of the other types of sources you use in your essay.

2 Read all the sources carefully

A synthesis essay is only as good as its sources. The nature of a synthesis essay is to build on its sources, so you need to choose the best ones and understand each of them thoroughly.

Make sure you comb through your sources so you don’t miss a good point or piece of evidence you could use in your essay. It helps to come up with your thesis statement early on so you can look for points related to it when you’re reading.

3 Write a gripping introduction

One of the keys to any good essay, synthesis or not, is a strong opening. This is partially determined by your thesis statement, but the other sentences in your introduction also make a big impact.

For starters, you can learn how to write a hook . In writing, a hook is something that grabs the reader’s attention and makes them want to keep reading. Hooks can essentially be anything interesting. Some common strategies for writing hooks include using personal anecdotes to create an emotional connection or providing exciting facts/statistics that the reader might not know.

Additionally, the introduction should also explain the scope of your topic and set the scene for people who aren’t familiar with it. The goal of the introduction is to prepare the reader for what follows so that afterward you can transition straight into making your points.

Synthesis essay vs. argumentative essay

Synthesis essays are often compared to argumentative essays, which attempt to refute, debunk, or criticize existing ideas or other research. The truth is that the two are not mutually exclusive. Although synthesis essays tend to be analytical or expository, they can also be argumentative.

A synthesis essay is any essay that combines ideas from multiple sources to create a new unified idea. If that new idea is a rebuttal to a preexisting idea and the entire essay is written as a critique, then the essay would be both synthesis and argumentative.

Synthesis essay FAQs

A synthesis essay is a type of essay that combines points, data, and evidence from multiple sources and turns them into one unified idea. In other words, the writer synthesizes their own idea using other sources’ research and ideas.

What is a good synthesis essay structure?

Traditionally, the common approaches to creating a synthesis essay structure are organizing by topic or organizing by source. The former means you discuss each source’s perspective on a topic before moving to the next topic; the latter means you discuss one source’s stance on each topic and then move to another source. You can also create a hybrid structure of the two for particular subjects.

What is the difference between a synthesis essay and an argumentative essay?

Synthesis essays are often contrasted with argumentative essays, but the truth is that the two are not mutually exclusive. For example, an argumentative essay can use the format of a synthesis essay—combining points from multiple sources to form a new unified idea—in order to refute a preexisting idea.

Synthesis Essays: A Step-by-Step How-To Guide

A synthesis essay is generally a short essay which brings two or more sources (or perspectives) into conversation with each other.

The word “synthesis” confuses every student a little bit. Fortunately, this step-by-step how-to guide will see you through to success!

Here’s a step-by-step how-to guide, with examples, that will help you write yours.

Before drafting your essay:

After reading the sources and before writing your essay, ask yourself these questions:

  • What is the debate or issue that concerns all of the writers? In other words, what is the question they are trying to answer?
  • On what points do they agree?
  • On what points do they disagree?
  • If they were having a verbal discussion, how would writer number one respond to the arguments of writer number two?

In a way, writing a synthesis essay is similar to composing a summary. But a synthesis essay requires you to read more than one source and to identify the way the writers’ ideas and points of view are related.

Sometimes several sources will reach the same conclusion even though each source approaches the subject from a different point of view.

Other times, sources will discuss the same aspects of the problem/issue/debate but will reach different conclusions.

And sometimes, sources will simply repeat ideas you have read in other sources; however, this is unlikely in a high school or AP situation.

To better organize your thoughts about what you’ve read, do this:

  • Identify each writer’s thesis/claim/main idea
  • List the writers supporting ideas (think topic sentences or substantiating ideas)
  • List the types of support used by the writers that seem important. For example, if the writer uses a lot of statistics to support a claim, note this. If a writer uses historical facts, note this.

There’s one more thing to do before writing: You need to articulate for yourself the relationships and connections among these ideas.

Sometimes the relationships are easy to find. For example, after reading several articles about censorship in newspapers, you may notice that most of the writers refer to or in some way use the First Amendment to help support their arguments and help persuade readers. In this case, you would want to describe the different ways the writers use the First Amendment in their arguments. To do this, ask yourself, “How does this writer exploit the value of the First Amendment/use the First Amendment to help persuade or manipulate the readers into thinking that she is right?

Sometimes articulating the relationships between ideas is not as easy. If you have trouble articulating clear relationships among the shared ideas you have noted, ask yourself these questions:

  • Do the ideas of one writer support the ideas of another? If so, how?
  • Do the writers who reach the same conclusion use the same ideas in their writing? If not, is there a different persuasive value to the ideas used by one writer than by the other?
  • Do the writers who disagree discuss similar points or did they approach the subject from a completely different angle and therefore use different points and different kinds of evidence to support their arguments?
  • Review your list of ideas. Are any of the ideas you have listed actually the same idea, just written in different words?

Are you writing a synthesis essay? This is a paper that combines information from a variety of sources to form a new idea. Essentially, you’re synthesizing existing concepts and arguments to create something original.

As a student, you’ll probably have to write a synthesis essay at some point. Read on for our step-by-step guide on how to write one effectively.

Step 1. Define Your Idea or Argument

If you haven’t done so already, decide on a topic to write about. Read up about it using a variety of credible sources and make detailed notes while you research. Make sure you keep track of the sources you decide to pull information from so that you can cite them properly later.

Make a list of key points from your research. Once you have a good selection of material to work with, start developing your own idea or argument. This will be the focus of your essay.

Step 2. Create an Outline

Synthesis essays generally follow this format: an introduction, a handful of main body paragraphs, and a conclusion. It’s a good idea to come up with an essay plan before you start writing so that you can keep things organized while you work.

The outline is mainly helpful for deciding what to include in your body paragraphs. Decide what supporting points (and counterarguments ) from your research you want to include, and which order you want to discuss them in. You should have enough information to flesh out one paragraph for each point.

Step 3. Write Your Introduction

In your introduction, you should open with something that hooks the reader and captures their attention. Then, state your argument or idea (i.e., your thesis statement) and briefly summarize the material you’ll be including in your essay. You should also include any relevant background information here.

Step 4. Write the Body Paragraphs

Using your outline, discuss each point from your source material in more depth, devoting a body paragraph to each. Explain the information from the outside source, including appropriate citations, and discuss how it connects with your idea.

It’s a good idea to mostly focus on points that support your argument, but you should also include a paragraph with a counterargument or two. This means discussing a perspective that doesn’t necessarily align with your idea, and then explaining why your argument still works.

Step 5. Tie It All Together With a Conclusion

The conclusion should leave the reader feeling convinced of your idea. Restate your point clearly and summarize the main points you’ve discussed. You could also offer any concluding reflections on the topic.

Different Types of Synthesis Essays

While you can follow our steps for any type of synthesis essay, yours will probably fall under one of two categories: explanatory or argumentative.

Argumentative essays are as they sound – they present an argument. With an argumentative essay, you’ll take a more definitive stance on something and use your supporting material to persuade the reader.

Explanatory essays don’t necessarily take a side one way or the other. Rather, they focus on developing and explaining a concept thoroughly. Knowing which type of essay you’re writing will help you to gather more effective source material for your purpose.

Cite Your Sources

Since synthesis essays are particularly dependent on outside material, it’s especially important that you cite your sources correctly. Familiarize yourself with your referencing system before you start researching so you know what information you need to keep track of, and include appropriate citations whenever you use someone else’s work.

At the end of the essay, you’ll need to compile your sources into a reference list following the requirements of your style guide.

Summary: Writing a Synthesis Essay

Hopefully, this post has helped you to feel more confident in writing a synthesis essay. Choose a topic first, do your research, keep track of your sources, and develop an argument or idea. From there, you can organize your thoughts into an outline and get to writing!

Synthesis Essay Thesis Statement

A strong thesis statement for a synthesis essay is more nuanced than a simple opinion. It acknowledges the complexities of the topic and positions your essay as a bridge between existing perspectives. Here's how to craft an effective thesis:

  • Avoid extremes: Statements like "Social media is destroying society" are too broad and lack specific arguments. Saying "Taxes are bad" ignores potential benefits or complexities.
  • Acknowledge Nuance: Show you understand different viewpoints by using qualifiers like "often," "in some cases," or "to a certain extent."
  • Bridge the Gap: Your thesis should connect various source viewpoints to create a new perspective.

Example transformation:

Original (weak): Video games are a waste of time.

Improved: While video games can be a source of leisure, their excessive use can negatively impact academic performance and social interaction. (This acknowledges the entertainment value while highlighting potential drawbacks.)

  • Your thesis should be specific to your topic and the sources you'll use.
  • It should be clear, concise, and directly address the prompt.
  • It sets the stage for your argument by outlining the connections between your chosen sources.

27 How do I Write a Synthesis Essay?

A synthesis essay is a type of essay that gathers information from a variety of sources to form a new idea, question, or argumentative thesis. Writers composing a synthesis essay will discuss ideas, data, and evidence from a series of sources to either explain or argue something original.

Explanatory vs. Argumentative Synthesis Essays: How Are They Different?

Though the formatting is largely the same, there are two main types of synthesis essays: explanatory and argumentative.

  • 1.   Explanatory : The purpose of an explanatory synthesis essay is to use different sources to explain a particular point of view. These synthesis papers objectively examine the similarities and differences between ideas but don’t necessarily choose a side or attempt to sway the reader in any direction.
  • 2.   Argumentative : An argumentative synthesis essay follows the same structure as a typical argumentative essay. The thesis of an argumentative essay will argue one specific point.

Synthesis Essay Structure

Synthesis essays typically adhere to the five-paragraph essay structure, but there are slight nuances to structuring this type of essay. Here is how a synthesis essay is structured.

  •   Introduction : The foundational ideas of your essay are expressed in the introductory paragraph. You will address the general landscape of ideas around your topic, introducing some of your sources. You will also introduce the argument to be made through a thesis statement, which succinctly states your primary argument in a sentence or two. The thesis statement typically comes at the very end of your introductory paragraph.
  •   Body : The body of your synthesis essay is usually about three paragraphs long. This typically includes two paragraphs synthesizing your sources in a way that supports your argument, and one paragraph that acknowledges opposing arguments.
  • Conclusion : The conclusion of your synthesis essay reiterates the argument that you’ve made throughout your essay. It may emphasize how each of the points you made and the sources you’ve cited substantiate your point.

How to Write a Synthesis Essay

A great synthesis essay walks readers through a series of ideas and sources to prove or explain a larger point.

Follow this step-by-step guide for writing your essay:

  • Choose a topic you’re curious about . Brainstorm a few ideas for your synthesis essay topic, prioritizing the subjects you feel passionate about.
  • Do your research . Once you’ve decided on a topic, use the internet, library, and other sources to perform extensive research. You can turn to academic primary sources to find quotes from scholars and experts, or look up statistics or scientific studies relevant to your topic. This research will help you develop a point of view that is backed up by concrete information. Use credible sources that are unbiased.
  • Outline your point . Your entire essay should focus on either explaining a certain perspective or making an argument. Outline how each of your sources relates to your theme and support your idea.
  • Write your introduction . An introduction is the first paragraph of a paper. Its main purpose is to present the general premise of the paper, provide any necessary background information, and hopefully, capture the reader’s attention. The introductory paragraph to your synthesis essay should be where you include a strong thesis statement. This is where you will state the point of view that you’re exploring or the argument you’re making.
  • Include your body paragraphs . Synthesis essays will typically contain three body paragraphs. A good body paragraph contains three main sections: a topic sentence (or key sentence), relevant supporting  sentences, and a closing (or transition)
  • sentence. This structure keeps your paragraph focused on the main idea, providing clear, concise information. Each body paragraph should discuss different elements and supporting arguments of your thesis, along with evidence drawn from each source. Explain the common theme between your resources, as well as how they are relevant to your text. Include counterarguments as well as how your source material can discredit those claims and support your own idea.
  • Wrap it up with a strong conclusion . A conclusion is a final piece of writing in a research paper, essay, or article that summarizes the entire work. The concluding paragraph of your synthesis essay will restate your thesis, summarize the key supporting ideas you discussed throughout the work, and offer your final impression of the central idea.
  • Proofread . Always proofread your writing a few times before submitting or presenting it. A few missed words or grammatical errors can sometimes change or discredit the entire crux of an argument or opinion. Make sure that your grammar, syntax, and flow are as accurate and clear as possible. This will help you come across as a credible source.
