Build a paragraph around a claim and evidence

A paragraph becomes useful when its evidence helps a reader understand or assess a particular point. A quotation followed by another quotation may contain relevant material but leave the connection for the reader to supply.

Start by deciding what the paragraph needs to establish. Then choose evidence that bears on that point and explain the connection. This guide works through those decisions using an invented example, so you can see the writing develop without needing specialist subject knowledge.

Give the paragraph a specific job

Suppose an assignment asks you to assess a proposal to extend a college library’s opening hours. “Library opening hours” is a topic, but it does not yet tell you what a paragraph will contribute to the answer.

A more useful working claim is:

The proposed extension would create a study period after classes for students on the evening course.

That claim sets a manageable task. You now need evidence about the course timetable and the current and proposed closing times. You do not yet need to prove that longer opening hours improve grades or that the proposal is affordable. Those are different questions.

Harvard’s Anatomy of a Body Paragraph identifies a topic sentence, evidence and analysis as common elements of a strong academic paragraph. The topic sentence also helps place the paragraph within the larger argument. Here, the larger question is whether to extend opening hours; this paragraph addresses one consideration: access after evening classes.

Choose evidence that answers the claim

For this demonstration, imagine an assignment pack containing two documents:

Fictional document A: an evening-course timetable showing classes ending at 19:30 on Tuesdays and Thursdays.
Fictional document B: a library proposal stating that closing time on those evenings would move from 19:00 to 21:00.

These documents and details are invented teaching material, not real research or citations. In your own assignment, use sources you have actually read and cite them in the required style, including locators where needed.

When the evidence comes from a published source, paraphrase its claim accurately before fitting it into your paragraph; preserve its scope, uncertainty and attribution.

Both documents are necessary to this particular comparison. Document B alone tells us about a later closing time; document A explains why it matters to this group. A general source praising libraries would be less direct evidence for the claim about access after class.

Keep a note beside each source: “What can this establish?” For document A, the answer is the scheduled end of classes. It does not establish whether students want to stay, have transport home or would use the library.

Write the missing reasoning

A first attempt might read:

The extension would help evening-course students. Classes finish at 19:30 on Tuesdays and Thursdays (fictional document A). The library currently closes at 19:00 and would close at 21:00 under the proposal (fictional document B).

The facts are relevant, but “help” remains vague. Make the relationship explicit:

Under the current timetable, the library closes before these classes finish. The proposed closing time would leave a 90-minute window after class, before allowing for the time needed to reach the library.

This is an explanation derived from the supplied times. It is not a new research finding. The calculation makes the access claim concrete, while the qualification avoids pretending that the whole window is necessarily available for study.

Try the same move in your own paragraph: identify the exact detail that matters, then explain how it changes the reader’s understanding of your claim. “This is important” usually leaves that work unfinished. Important to whom, for which reason, and in relation to what decision?

Read the assembled paragraph

The complete teaching example could read:

The proposed extension would create a study period after classes for students on the evening course. Their classes finish at 19:30 on Tuesdays and Thursdays (fictional document A), while the library currently closes at 19:00 and would close at 21:00 under the proposal (fictional document B). The current arrangement therefore provides no library access after those classes, whereas the proposal creates a 90-minute window before allowing for travel to the building. This supports the proposal on the specific criterion of access after class. It does not establish how many students would use that time, so the access benefit alone is insufficient to settle the broader decision about opening hours.

Notice the work each part does:

The opening identifies the contribution: access after a particular course, not every possible benefit of libraries.
The evidence supplies the relevant times: the reader can check the comparison against the two fictional documents.
The explanation draws out the consequence: the proposal creates an opportunity that the current schedule does not provide.
The ending limits the conclusion: opportunity is not evidence of actual use.

The last sentence leaves room for a separate paragraph about demand or cost. It does not introduce an unsupported claim that the extension will be popular or inexpensive.

For a different revision problem—an existing paragraph that makes claims beyond its evidence—see moving from description to critical analysis.

Use a structure without turning it into a sentence quota

You may have been taught PEEL: point, evidence, explanation and link. It can help you notice a missing function. It does not require every paragraph to contain exactly four sentences or one quotation.

Sheffield’s paragraph guidance presents its model as adaptable and suggests splitting a paragraph when it drifts into another idea. Follow any specific structure your instructor requires; otherwise, judge whether the reader can follow the reasoning.

In the library example, adding a detailed staffing-cost comparison would probably create a second job for the paragraph. Move it to a new paragraph and explain how that criterion contributes to the overall assessment. Adding another relevant timetable detail may instead belong within the same paragraph.

Check one paragraph before polishing the whole draft

Underline the sentence that states your main point. Mark the evidence and circle the words that explain its relevance. Then ask:

Can I say what this paragraph contributes to the assignment in one sentence?
Does the evidence address that contribution, or merely mention the same topic?
Have I shown the reader the connection instead of relying on a citation to do it?
Does my conclusion stay within what the evidence can establish?
Would a new reader understand why the paragraph belongs here?

If the evidence does not support the opening claim, revise the claim or find better evidence before polishing the wording. Use the claim–evidence fit audit when the problem concerns the measure, population, comparison or strength of inference rather than the paragraph’s assembly. Our guide to academic editing and proofreading explains why argument-level revision and final language checks are different tasks.
