How to Write a Body Paragraph: Topic Sentence, Evidence, Analysis, and Link
Learn how to write strong body paragraphs for any essay using a four-part structure: topic sentence, evidence, analysis, and link. Includes annotated examples, a weak-to-strong revision, length guidelines, and a checklist.
Your introduction makes a promise. Your body paragraphs keep it. However strong your thesis is, the reader will judge your essay mostly on what happens in the middle: whether each paragraph makes a clear point, supports it, and explains why it matters.
The good news is that almost every effective body paragraph, in almost every kind of essay, follows the same basic pattern. Once you learn it, you can write paragraphs that are focused, convincing, and easy to follow, then adjust the pattern as your writing grows more confident.
What a Body Paragraph Does
A body paragraph develops one point that supports your thesis. One paragraph, one idea. If your thesis is the roof, each body paragraph is a pillar holding it up.
That gives every body paragraph three jobs:
- Make a claim that supports the thesis.
- Prove it with evidence.
- Explain it so the reader sees how the evidence supports the claim.
When a paragraph feels weak, one of these three jobs is usually missing. The most common gap is the third: writers present evidence and assume it speaks for itself. It almost never does.
The Four-Part Structure
Teachers use many acronyms for this pattern: PEEL, PEAL, TEEL, MEAL. They all describe the same moves. This guide uses four plain names.
| Part | What it does | Typical length |
|---|---|---|
| Topic sentence | States the paragraph’s single main point | 1 sentence |
| Evidence | Supplies a quotation, fact, example, or data | 1–2 sentences |
| Analysis | Explains what the evidence shows and why it matters | 2–4 sentences |
| Link | Connects back to the thesis or forward to the next point | 1 sentence |
Notice that analysis gets the most space. That’s deliberate. Evidence is borrowed; analysis is where your own thinking appears, and it’s what teachers grade most heavily.
Part 1: The Topic Sentence
The topic sentence tells the reader exactly what the paragraph will prove. It works like a mini-thesis for the paragraph.
A strong topic sentence:
- Makes a claim, not just an announcement of the topic.
- Connects to the thesis, using a key word or idea from it.
- Is specific enough to prove in one paragraph.
Suppose your thesis is: Public libraries remain essential because they provide free internet access, quiet study space, and programs that connect isolated residents.
- Weak: This paragraph is about internet access. (Announces a topic, makes no claim.)
- Weak: The internet is very important today. (True, but disconnected from libraries and the thesis.)
- Strong: For residents without home broadband, the library is often the only place to complete tasks that now happen almost entirely online.
The strong version makes an arguable claim, links to the thesis (internet access, essential), and sets up exactly what the evidence will need to show.
Tip: Draft your topic sentences first, as a list, before writing any paragraph in full. If you read only your topic sentences in order, they should sum up your whole argument. If they don’t, fix your essay outline before you draft.
Part 2: The Evidence
Evidence is the proof. What counts as good evidence depends on the essay:
- Literary analysis: short quotations from the text, with page or line numbers
- Argumentative and persuasive essays: statistics, research findings, expert views, real examples
- Expository essays: facts, definitions, processes, and examples
- Personal or reflective essays: specific moments, details, and dialogue from your experience
Three rules make evidence work:
- Introduce it. Never drop a quotation into a paragraph without a lead-in. Tell the reader who said it or where it comes from.
- Keep it short. Quote only the words you’ll actually analyze. Paraphrase the rest.
- Cite it. Follow the format your assignment requires. Our guide to citing sources in MLA and APA covers the basics.
Dropped quotation:
Libraries help job seekers. “Many employers accept applications only online.”
Introduced quotation:
A local workforce report notes that “many employers accept applications only online,” which means a job seeker without internet access may not be able to apply at all.
(The report here is a placeholder. In a real essay, name and cite an actual source.)
Part 3: The Analysis
Analysis answers the question every reader silently asks after evidence: so what?
Good analysis does at least one of these:
- Explains what the evidence means in plain terms
- Interprets a detail the reader might miss
- Connects the evidence directly to the claim in your topic sentence
- Considers implications: what follows if this evidence is true
Sentence starters can help you push past summary:
- This shows that…
- This matters because…
- The word ”___” suggests…
- As a result, …
- Without this, …
- This detail reveals…
A useful test: if you deleted your evidence, would your analysis still make sense on its own? It shouldn’t. Analysis should be tied so tightly to the evidence that it can’t survive without it. And if you deleted your analysis, the paragraph should feel noticeably weaker. If it doesn’t, you’ve written summary, not analysis.
Part 4: The Link
The final sentence closes the paragraph’s argument and ties it back to the bigger picture. It can:
- Look back to the thesis: For these residents, then, the library isn’t a convenience but a necessity.
- Look forward to the next paragraph: Yet access to a computer is only useful if there’s somewhere to concentrate, and that’s the library’s second essential role.
Avoid simply repeating your topic sentence word for word. The link should show what the paragraph has added, not restate where it began. Transition words such as therefore, as a result, and yet help signal the relationship.
A Complete Annotated Example
Here is a full body paragraph built on the library thesis, with each part labeled. All details are illustrative; a real essay would cite real sources.
[Topic sentence] For residents without home broadband, the library is often the only place to complete tasks that now happen almost entirely online. [Evidence] Job applications, benefit renewals, school assignments, and even some medical appointments increasingly require an internet connection and a working computer, and a phone screen is a poor tool for filling out a ten-page form or writing a résumé. [Analysis] This means the shift to online services hasn’t removed barriers for everyone; it has moved them. A person who once needed transportation to an office now needs a device and a connection instead. For someone who has neither, the library’s free computers are not an extra perk but the only route to services the rest of the community takes for granted. [Link] Free internet access, then, is the clearest example of how the library fills gaps that would otherwise leave residents shut out.
Count the parts: one topic sentence, one sentence of evidence, three sentences of analysis, one link. The analysis outweighs the evidence, which is exactly what you want.
Revising a Weak Body Paragraph
Here is a typical first-draft paragraph from a literary essay on a short story:
Before: In the story, the main character is lonely. She eats dinner alone every night. She also doesn’t talk to her neighbors. At the end, she starts talking to a neighbor. This shows she changes.
What’s wrong:
- The topic sentence states a fact, not a claim.
- The evidence is summary, not specific quotation or detail.
- The analysis is one vague sentence.
- There’s no link to a thesis.
After: The story uses the protagonist’s dinner routine to show that her loneliness is self-protective rather than accidental. Early on, she sets “one plate, one glass, one fork” on a table built for six, and the repetition of “one” makes the emptiness feel deliberate, almost like a rule she has written for herself. The extra chairs suggest a life that once included others, so her solitude reads less as circumstance than as a choice to avoid being hurt again. When she finally carries a second plate to her neighbor’s door in the last scene, the same object that marked her isolation becomes her first gesture of connection. Her change, then, is not that she stops being alone but that she stops choosing to be.
(The story and quotation here are invented for illustration.)
The revised version makes an interpretive claim, quotes a precise detail, analyzes word choice and imagery, and ends with an insight that would connect to the essay’s thesis.
How Long Should a Body Paragraph Be?
For most high school and college essays, five to eight sentences, or about 100 to 200 words, is a healthy range. But length should follow function:
- Too short (two or three sentences) usually means the analysis is missing.
- Too long (more than a page) usually means the paragraph is trying to make two points. Split it at the place where the main idea changes.
In a standard five-paragraph essay, you’ll write three body paragraphs. Longer essays simply use more of them, one per supporting point.
Common Body Paragraph Mistakes
- Starting with a quotation. Lead with your claim; let the evidence follow.
- Summarizing instead of analyzing. Retelling what happens isn’t the same as explaining what it means.
- Two ideas in one paragraph. If you use “also” to introduce a whole new point, you probably need a new paragraph.
- Evidence with no lead-in. Every quotation needs a frame.
- Ending on evidence. Never let a quotation be the last sentence. Your voice should close the paragraph.
- Losing the thesis. Each paragraph should clearly support the thesis, not just the topic.
Body Paragraph Checklist
- Does the topic sentence make a claim that supports my thesis?
- Does the paragraph focus on one main idea?
- Is my evidence specific, introduced, and cited?
- Is my analysis longer than my evidence?
- Does the analysis explain how the evidence proves the claim?
- Does the final sentence link back to the thesis or forward to the next point?
- Could a reader understand the paragraph’s point from the first sentence alone?
Practice Exercise
Take one body paragraph from an essay you’ve already written. Using four different highlighter colors, mark the topic sentence, evidence, analysis, and link. Then look at the colors. Is analysis your largest color? If evidence dominates, or if one color is missing, rewrite the paragraph so each part is present and analysis takes up at least half the space. Read the old and new versions aloud and notice which one sounds like your thinking. Once all your paragraphs are solid, use our guide on how to proofread and edit your essay to polish the full draft.
