Writing Body Paragraphs

Author: Sophia

what's covered
In this lesson, you will examine the structure and components of a body paragraph and explore some strategies for writing strong paragraphs. Specifically, this lesson will cover:

Table of Contents

1. Topic Sentence

The topic sentence tells the reader what your paragraph is about and the main idea of that paragraph. The topic sentence should usually be the first sentence of your paragraph. It might actually take two sentences to introduce a topic and map out where you are going in a paragraph. It depends on the length of the paragraph and the ideas you are working through.


2. Evidence and In-Text Citations

You will need to make claims and introduce evidence in many of your paragraphs because you are writing a persuasive essay. One common way to do that is to use short quotations. Start by introducing the source and reason for the quotation in a phrase or sentence. Readers should be able to follow your meaning easily and to understand the relevance of the quotation immediately.

Remember that for each quote you choose, you should focus your reader's attention on the aspect most important to the topic sentence in that paragraph. Because readers need to know that you are moving from your words or ideas to an outside source, introduce quoted material with a signal phrase. A signal phrase is a word or group of words that introduces paraphrased or quoted material and informs readers of the source.

EXAMPLE

As Henry David Thoreau asserts in Walden, “the mass of men lead lives of quiet desperation” (5).

Notice the signal phrase in this example, which appears before the quotation.

EXAMPLE

Walden sets forth one individual’s antidote against the ‘lives of quiet desperation’ led by the working class in mid-nineteenth-century America” (Thoreau 5).

In this example, the paper focuses on the published work itself, so the author introduces a quotation with the work’s title rather than the author’s name, and the reference is still clear.

EXAMPLE

“Mary Catherine Bateson, daughter of renown anthropologist Margaret Mead, has become, in her own right, a student of modern civilization.”

In this example, the author or the source is not well-known, so the quotation is introduced with a brief explanation which gives readers enough context to understand the quotation.

Keep in mind that a signal phrase can also tell the reader what the words in the quotation are doing. Are they explaining or defending? Are they noting or considering? They also move the reader from your words to the words of a quotation smoothly. The signal phrase provides a clear signal that a quote is coming, followed by the quotation. Take a look at some suggestions for signal words:

acknowledges denies points out
admits emphasizes proves
agrees endorses refutes
argues follows up reports
asserts grants reveals
believes illustrates says
claims implies shows
comments insists states
concedes maintains suggests
concludes notes thinks
declares observes writes

Remember that your evidence must specifically support your claim. This means you will need to plan for where you are going to put your evidence. In what order will it appear convincing? One strategy for planning out the evidence you will use is to start copying and pasting parts of your annotations into your outline for your paper. You will need to include the bibliographic information here as well, as part of your in-text citation.

An in-text citation is a brief reference within the text of your essay or assignment that indicates the source of information or ideas you have used. It requires less bibliographic information than a reference page entry. According to APA guidelines, in-text citations must include the following bibliographic data:

  • The author's last name
  • The year when the source was published
  • The page or paragraph number where the quoted or paraphrased material is located (if available)
We’ll explore how to create in-text citations in the future tutorials.

EXAMPLE

Walden sets forth one individual’s antidote against the ‘lives of quiet desperation’ led by the working class in mid-nineteenth-century America” (Thoreau 5).

Notice the author’s last name is in parentheses, followed by the page number where the quotation can be found.

terms to know
Signal Phrase

In-Text Citation
Sources used or cited in an essay through quoting, summarizing, and paraphrasing, so-called because they appear within the text of the essay itself (as opposed to in footnotes or on a references page).


3. Summary, Analysis, and Synthesis

As you are starting to write your first draft, you can start expanding the summary in your annotated bibliography entries for a few key sources. You may find that there are a couple of sources that are really important for your reader to understand. If this is true for you, you will want to introduce those key sources early in your paper to give your reader a sense of context.

For most of your sources, though, you will probably not need to summarize them for more than a sentence or two. Analysis will be the larger part of using these sources. You may want to think about which sources will pair well together so that you can compare and contrast, which can help your reader get a clear sense of what is going on in an argument.

We have already talked about the role of synthesis in your thesis statement, but you will also need to do some synthesis work in your body paragraphs. Your thesis will not be your only original claim you are making. You may, for instance, argue that a specific source needs to be updated by further research because some other source has made a new discovery. This is synthesis! You are putting two things together to make something new! You may also find that you need to make something new because you need to adapt source material for a new audience. There are lots of opportunities for synthesis in body paragraphs where you are doing this kind of work. We will explore strategies for summary, analysis, and synthesis in later tutorials.


4. Concluding Sentence

While the first sentence of a paragraph will do a lot of transition work for you, your final sentence of the previous paragraph can be a great place to set up where you are going next. You don’t want to introduce the next topic at the end of a paragraph, but you can help your reader see where you are going.


5. Remember to Check for Validity

After you have completed a body paragraph, check the validity, or soundness, of your logic. To perform this check, begin by assessing the logical connection of your topic sentences to your thesis statement. Because the topic sentences are the major supporting statements for your thesis, each one should support it. Ask and answer the following questions of each topic sentence:

  • Does this topic sentence reflect the reasoning strategy you are using?
  • Does this topic sentence directly support the thesis statement?
  • Does the topic sentence make a sensible point?
  • What is the topic sentence’s purpose? Is it to provide background information? A reason? An illustration? An explanation? A response to a counterclaim?
If you have trouble answering any of the questions and cannot establish the sentence’s validity, consider revising the topic sentence.

Next, check the validity of your body paragraphs’ development. To perform this check, answer these questions on all the major supporting ideas that you develop for each topic sentence:

  • Does this body paragraph reflect the reasoning strategy you are using?
  • Does developing the idea in this body paragraph directly support its topic sentence?
  • Does this idea make a sensible point?
  • What is the purpose of developing this idea? Is it to provide background information? A reason for the topic sentence’s claim? An illustration of the topic sentence’s point? An explanation of the sentence’s point? Evidence demonstrating the topic sentence’s point?
If you have trouble answering any of the questions and cannot establish a supporting idea’s validity, consider revising or replacing the idea with one that you can logically develop to prove, illustrate, or explain the topic idea.

summary
In this lesson, you learned how to build strong, focused body paragraphs that drive your persuasive essay forward. Each paragraph should begin with a clear topic sentence that maps out the main idea and sets up what the paragraph will accomplish. Following this, it’s important to introduce evidence and in-text citations to smoothly connect your ideas to outside references. A well-chosen signal phrase not only credits the source but also clarifies how the evidence supports your argument, ensuring the reader stays oriented.

You also reviewed the need to plan ahead with evidence and outside sources, using strategies like inserting parts of your annotated bibliography into your outline to maintain clear organization. As you draft, you’ll rely on a balance of summary, analysis, and synthesis: summarizing only when necessary, analyzing to show deeper understanding, and synthesizing to combine ideas into something new and original. Finally, you learned that a body paragraph’s concluding sentence can act as a bridge to the next idea, helping your essay flow smoothly without prematurely introducing the next topic. Remember to check for validity so that you craft persuasive, coherent paragraphs that strengthen your overall argument.
