Abstract

An abstract is a self-contained summary of a larger work, such as research and scientific papers or general academic papers. Usually situated at the beginning of such works, the abstract is meant to “preview” the bigger document. This helps readers and other researchers find what they’re looking for and understand the magnitude of what’s discussed. 

Like the trailer for a movie, an abstract can determine whether or not someone becomes interested in your work. Aside from enticing readers, abstracts are also useful organizational tools that help other researchers and academics find papers relevant to their work.  

Because of their specific requirements, it’s best to know a little about how to write an abstract before doing it. This guide explains the basics of writing an abstract for beginners, including what to put in them and some expert tips on writing them. 

What’s the purpose of an abstract?

The main purpose of an abstract is to help people decide whether or not to read the entire academic paper. After all, titles can be misleading and don’t get into specifics like methodology or results. Imagine paying for and downloading a hundred-page dissertation on what you believe is relevant to your research on the Caucasus region—only to find out it’s about the other Georgia. 

Likewise, abstracts can encourage financial support for grant proposals and fundraising. If you lack the funding for your research, your proposal abstract would outline the costs and benefits of your project. This way, potential investors could make an informed decision, or jump to the relevant section of your proposal to see the details. 

Abstracts are also incredibly useful for indexing. They make it easier for researchers to find precisely what they need without wasting time skimming actual papers. And because abstracts sometimes touch on the results of a paper, researchers and students can see right away if the paper can be used as evidence or a citation to support their own theses. 

Nowadays, abstracts are also important for search engine optimization (SEO)—namely, for getting digital copies of your paper to appear in search engine results. If someone Googles the words used in your abstract, the link to your paper will appear higher in the search results, making it more likely to get clicks. 

How long should an abstract be? 

Abstracts are typically 100–250 words and comprise one or two paragraphs. However, more complex papers require more complex abstracts, so you may need to stretch it out to cover everything. It’s not uncommon to see abstracts that fill an entire page, especially in advanced scientific works. 

When do you need to write an abstract? 

Abstracts are only for lengthy, often complicated texts, as with scientific and research papers. Similar academic papers—including doctorate dissertations, master’s theses, or elaborate literary criticisms—may also demand them as well. If you’re learning how to write a thesis paper for college, you’ll want to know how to write an abstract, too. 

Specifically, most scientific journals and grant proposals require an abstract for submissions. Conference papers often involve them as well, as do book proposals and other fundraising endeavors. 

However, most writing, in particular casual and creative writing, doesn’t need an abstract. 

Types of abstracts

There are two main types of abstracts: informative and descriptive. Most abstracts fall into the informative category, with descriptive abstracts reserved for less formal papers. 

Informative abstracts

Informative abstracts discuss all the need-to-know details of your paper: purpose, method, scope, results, and conclusion. They’re the go-to format for scientific and research papers. 

Informative abstracts attempt to outline the entire paper without going into specifics. They’re written for quick reference, favor efficiency over style, and tend to lack personality. 

Descriptive abstracts

Descriptive abstracts are a little more personable and focus more on enticing readers. They don’t care as much for data and details, and instead read more like overviews that don’t give too much away. Think of descriptive abstracts like synopses on the back of a book. 

Because they don’t delve too deep, descriptive abstracts are shorter than informative abstracts, closer to 100 words, and in a single paragraph. In particular, they don’t cover areas like results or conclusions — you have to read the paper to satisfy your curiosity. 

Since they’re so informal, descriptive abstracts are more at home in artistic criticisms and entertaining papers than in scientific articles. 

What to include in an abstract

As part of a formal document, informative abstracts adhere to more scientific and data-based structures. Like the paper itself, abstracts should include all of the IMRaD elements: Introduction, Methods, Results, and Discussion. 

This handy acronym is a great way to remember what parts to include in your abstract. There are some other areas you might need as well, which we also explain at the end. 

Introduction

The beginning of your abstract should provide a broad overview of the entire project, just like the thesis statement. You can also use this section of your abstract to write out your hypothesis or research question. 

In the one or two sentences at the top, you want to disclose the purpose of your paper, such as what problem it attempts to solve and why the reader should be interested. You’ll also need to explain the context around it, including any historical references. 

Methods

This section covers the methodology of your research, or how you collected the data. This is crucial for verifying the credibility of your paper — abstracts with no methodology or suspicious methods won’t be taken seriously by the scientific community. 

If you’re using original research, you should disclose which analytical methods you used to collect your data, including descriptions of instruments, software, or participants. If you’re expounding on previous data, this is a good place to cite which data and from where to avoid plagiarism. 

Results

For informative abstracts, it’s okay to “give away the ending.” In one or two sentences, summarize the results of your paper and the conclusive outcome. Remember that the goal of most abstracts is to inform, not entice, so mentioning your results here can help others better classify and categorize your paper. 

This is often the biggest section of your abstract. It involves most of the concrete details surrounding your paper, so don’t be afraid to give it an extra sentence or two compared to the others. 

Discussion

The discussion section explains the ultimate conclusion and its ramifications. Based on the data and examination, what can we take away from this paper? The discussion section often goes beyond the scope of the project itself, including the implications of the research or what it adds to its field as a whole. 

Other inclusions

Aside from the IMRaD aspects, your abstract may require some of the following areas:

• Keywords — Like hashtags for research papers, keywords list out the topics discussed in your paper so interested people can find it more easily, especially with online formats. The APA format (explained below) has specific requirements for listing keywords, so double-check there before listing yours. 
• Ethical concerns — If your research deals with ethically gray areas, i.e., testing on animals, you may want to point out any concerns here, or issue reassurances. 
• Consequences — If your research disproves or challenges a popular theory or belief, it’s good to mention that in the abstract — especially if you have new evidence to back it up. 
• Conflicts of Interest/Disclosures — Although different forums have different rules on disclosing conflicts of interests, it’s generally best to mention them in your abstract. For example, maybe you received funding from a biased party. 

If you’re ever in doubt about what to include in your abstract, just remember that it should act as a succinct summary of your entire paper. Include all the relevant points, but only the highlights. 

Abstract formats

In general, abstracts are pretty uniform since they’re exclusive to formal documents. That said, there are a couple of technical formats you should be aware of. 

APA format 

The American Psychological Association (APA) has specific guidelines for their papers in the interest of consistency. Here’s what the 7th edition Publication Manual has to say about formatting abstracts:

• Double-space your text.
• Set page margins at 1 inch (2.54 cm).
• Write the word “Abstract” at the top of the page, centered and in a bold font.
• Don’t indent the first line.
• Keep your abstract under 250 words.
• Include a running header and page numbers on all pages, including the abstract.

Abstract keywords have their own particular guidelines as well: 

• Label the section as “Keywords:” with italics.
• Indent the first line at 0.5 inches, but leave subsequent lines as is.
• Write your keywords on the same line as the label.
• Use lower-case letters.
• Use commas, but not conjunctions.

Structured abstracts

Structured abstracts are a relatively new format for scientific papers, originating in the late 1980s. Basically, you just separate your abstract into smaller subsections — typically based on the IMRaD categories — and label them accordingly. 

The idea is to enhance scannability; for example, if readers are only interested in the methodology, they can skip right to the methodology. The actual writing of structured abstracts, though, is more-or-less the same as traditional ones. 

Unstructured abstracts are still the convention, though, so double-check beforehand to see which one is preferred.

3 expert tips for writing abstracts

1 Autonomous works

Abstracts are meant to be self-contained, autonomous works. They should act as standalone documents, often with a beginning, middle, and end. The thinking is that, even if you never read the actual paper, you’ll still understand the entire scope of the project just from the abstract. 

Keep that in mind when you write your abstract: it should be a microcosm of the entire piece, with all the key points, but none of the details. 

2 Write the abstract last

Because the abstract comes first, it’s tempting to write it first. However, writing the abstract at the end is more effective since you have a better understanding of what is actually in your paper. You’ll also discover new implications as you write, and perhaps even shift the structure a bit. In any event, you’re better prepared to write the abstract once the main paper is completed. 

3 Abstracts are not introductions

A common misconception is to write your abstract like an introduction — after all, it’s the first section of your paper. However, abstracts follow a different set of guidelines, so don’t make this mistake. 

Abstracts are summaries, designed to encapsulate the findings of your paper and assist with organization and searchability. A good abstract includes background information and context, not to mention results and conclusions. Abstracts are also self-contained, and can be read independently of the rest of the paper. 

Introductions, by contrast, serve to gradually bring the reader up to speed on the topic. Their goals are less clinical and more personable, with room to elaborate and build anticipation. Introductions are also an integral part of the paper, and feel incomplete if read independently. 

Give your formal writing the My Fair Lady treatment

Formal papers — the kind that requires abstracts — need formal language. But for most of us, that means changing the way we communicate or even think. You may want to consider the My Fair Lady treatment, which is to say, having a skilled mentor coach what you say. 

Grammarly Premium now offers a new Set Goals feature that helps you tailor your language to your audience or intention. All you have to do is set the goals of a particular piece of writing and Grammarly will customize your feedback accordingly. For example, you can select the knowledge level of your readers, the formality of the tone, and the domain or field you’re writing for (i.e., academic, creative, business, etc.). You can even set a tone to sound more analytical or respectful! 

Conclusion

For many, the conclusion is the most dreaded part of essay writing. Condensing all the points you’ve analyzed in a tidy little package is certainly easier said than done. How can you make a good final impression while emphasizing the significance of your findings? 

Learning how to write a conclusion for an essay doesn’t need to feel like climbing Everest. It is wholly possible to tie everything together while considering the broader issues and implications of your argument. You just need the right strategy.

What do you want to leave your readers with? Perhaps you want to end with a quotation that adds texture to your discussion. Or, perhaps you want to set your argument into a different, perhaps larger context. 

An effective conclusion paragraph should ultimately suggest to your reader that you’ve accomplished what you set out to prove.

How to write a good conclusion

As you set out to write your conclusion and end your essay on an insightful note, you’ll want to start by restating your thesis. Since the thesis is the central idea of your entire essay, it’s wise to remind the reader of the purpose of your paper. 

Once you’ve restated your thesis (in a way that’s paraphrased, of course, and offers a fresh understanding), the next step is to reiterate your supporting points. Extract all of the “main points” from each of your supporting paragraphs or individual arguments in the essay. Then, find a way to wrap up these points in a way that demonstrates the importance of the ideas. 

Depending on the length of your essay, knowing how to write a good conclusion is somewhat intuitive—you don’t want to simply summarize what you wrote. Rather, the conclusion should convey a sense of closure alongside the larger meaning and lingering possibilities of the topic. 

What your conclusion should include

Now that you know what a good conclusion encompasses, you can get into the finer details. Beyond restating your thesis and summarizing your points, what else should the conclusion include?

Here are some strategies for ending your essay in a savvy and thought-provoking way: 

Ask yourself: “So what?” 

At some point in your life, a teacher has probably told you that the end of an essay should answer the question “So what?” or “Why does it matter?” This advice holds true. It’s helpful to ask yourself this question at the start of drafting your thesis and come back to it throughout, as it can keep you in tune with the essay’s purpose. Then, at your conclusion, you won’t be left searching for something to say.

Add perspective 

If you’ve come across a fantastic quote in your research that didn’t quite make it into the essay, the conclusion is a great spot for it. Including a quote from one of your primary or secondary sources can frame your thesis or final thoughts in a different light. This can add specificity and texture to your overall argument. 

For example, if you’ve written an essay about J.D. Salinger’s Catcher in the Rye, you can think about using a quote from the book itself or from a critic or scholar who complicates your main point. If your thesis is about Salinger’s desire to preserve childhood innocence, ending with a biographer’s statement about Salinger’s attitude toward his own youth might be illuminating for readers. If you decide to amplify your conclusion paragraph in this way, make sure the secondary material adds (and not detracts) from the points you already made. After all, you want to have the last word!

Consider the clincher

At the very end of the essay comes your closing sentence or clincher. As you think about how to write a good conclusion, the clincher must be top of mind. What can you say to propel the reader to a new view on the subject? This final sentence needs to help readers feel a sense of closure. It should also end on a positive note, so your audience feels glad they read your paper and that they learned something worthwhile. 

What your conclusion should not include

There are a few things that you should definitely strive to avoid when writing your conclusion paragraph. These elements will only cheapen your overall argument and belabor the obvious.

Here are several conclusion mishaps to consider:

• Avoid phrases like “in summary,” “in conclusion,” or “to sum up.” Readers know they’re at the end of the essay and don’t need a signpost. 
• Don’t simply summarize what’s come before. For a short essay, you certainly don’t need to reiterate all of your supporting arguments. Readers will know if you just copied and pasted from elsewhere.
• Avoid introducing brand new ideas or evidence. This will only confuse readers and sap force from your arguments. If there’s a really profound point that you’ve reached in your conclusion and want to include, try moving it to one of your supporting paragraphs. 

Whereas your introduction acts as a bridge that transfers your readers from their own lives into the “space” of your argument or analysis, your conclusion should help readers transition back to their daily lives. 

By following this useful roadmap, you can feel confident that you know how to write a good conclusion that leaves readers with a solution, a call to action, or a powerful insight for further study.
