Why outline
An outline shows whether every paragraph supports your thesis and whether you have enough evidence, while it is still easy to change. Purdue OWL names four parts of an effective outline: parallelism (headings in the same form), coordination (points of equal weight at the same level), subordination (details placed under the point they support), and division (each point split into at least two parts).
A template for a five-paragraph essay
| Section | What goes there | Example (prompt: should our town build a public pool?) |
|---|---|---|
| I. Introduction | Hook, a little background, thesis | Thesis: Our town should build a public pool because it would keep kids safe, create summer jobs, and bring families together. |
| II. Body 1 | Point 1 + evidence + what it shows | Safety: the nearest pool is 20 miles away; kids swim in the quarry instead. |
| III. Body 2 | Point 2 + evidence + what it shows | Jobs: lifeguards, swim teachers, snack bar staff, many of them local teens. |
| IV. Body 3 | Point 3 + evidence + what it shows | Community: swim meets, free swim nights, a place for families to meet. |
| V. Conclusion | Thesis in new words, why it matters | A safer, busier summer for the whole town. |
Weak vs strong outline points
| Weak | Strong | Why |
|---|---|---|
| II. Pools | II. A town pool would give kids a safe place to swim. | The strong point is a claim that supports the thesis. |
| III. History of swimming in ancient Rome | III. A pool would create summer jobs for local teens. | The weak point does not support the thesis at all. |
| IV. Community: it is nice | IV. A pool would give families a free place to meet. A: swim nights. B: swim meets. | The strong point has specific evidence under it. |
Worked examples
Example 1: build an outline from a prompt
Problem Prompt: Should students be required to learn a second language?
- Write a thesis: Schools should require two years of a second language, because it opens up jobs, helps students understand other cultures, and strengthens their English.
- Turn each reason into a body point written as a claim.
- Under each point, list the evidence you have or need to find: a statistic, an example, an expert source.
- Plan a counterargument (for example, it takes time from other classes) and your answer to it.
Answer Thesis, three claim-based body points with evidence under each, one counterargument, and a conclusion.
Example 2: a reverse outline of a draft
Problem You finished a draft and it feels messy. How do you check it?
- Next to each paragraph, write one short line: what is its main point?
- Read only those lines. Does each one support the thesis? Are any two the same?
- Move, merge or cut paragraphs based on what you see, then revise the thesis if your points changed.
Answer A reverse outline shows the structure you actually wrote, so you can fix it.
Common mistakes and fixes
| Mistake | Fix |
|---|---|
| Writing topics instead of claims | Turn each heading into a full sentence that takes a position. |
| Points that do not support the thesis | Cut them, or change the thesis to include them. |
| No evidence listed under a point | Add at least two specific details, or drop the point. |
| Skipping the outline for timed essays | Even two minutes of notes (thesis plus three points) saves time later. |
Practice
Five outline questions
In an outline, what should every body paragraph point back to?
- The thesis
- The title
- The hook
- The works cited list
Show answer
Answer: The thesis
Each body paragraph proves part of the thesis. The title and hook help the reader in, and the works cited list records sources, but none of them is what the paragraphs prove.
Thesis: Our town should build a public pool because it would keep kids safe, create summer jobs, and bring families together. Which point does NOT belong in the outline?
- Kids now swim in an unsafe quarry
- Swimming was popular in ancient Rome
- The pool would hire local teens as lifeguards
- Free swim nights would bring families together
Show answer
Answer: Swimming was popular in ancient Rome
It supports none of the three reasons in the thesis. Each other point matches one reason: safety, jobs or families.
In an outline, where does a piece of evidence go?
- After the conclusion
- Only in the introduction
- Under the point it supports
- Before the thesis
Show answer
Answer: Under the point it supports
Evidence is placed under the claim it proves. Purdue OWL calls this subordination. The other places separate evidence from the point it is supposed to support.
What is a reverse outline?
- An outline written starting from the conclusion
- A list of sources in reverse order
- An outline of the opposing side's argument
- An outline made from a finished draft, listing each paragraph's main point to check the structure
Show answer
Answer: An outline made from a finished draft, listing each paragraph's main point to check the structure
A reverse outline is a revision tool: you outline what you actually wrote and look for gaps, repeats and points that do not fit.
Under the point A town pool would create summer jobs, which detail fits best?
- The quarry has no lifeguard on duty.
- Swimming is good exercise for all ages.
- A pool would need lifeguards, swim teachers and snack bar workers, many of them local teens.
- Some families like to picnic on weekends.
Show answer
Answer: A pool would need lifeguards, swim teachers and snack bar workers, many of them local teens.
It names the actual jobs. Exercise, quarry safety and picnics are about health, safety and family time, which belong under other points or nowhere.
Frequently asked questions
Does an outline need full sentences?
Not always. A topic outline uses short phrases, and a sentence outline uses full sentences. Writing your thesis and each main point as full sentences is worth it, because those sentences become your thesis and topic sentences. Evidence can stay as short notes.
How long should an outline be?
Long enough to show your thesis, each main point, and the evidence under each. For a short essay that is often half a page. For a research paper, it can run a page or two, with sources noted next to each piece of evidence.
Can I change the outline while I write?
Yes. An outline is a plan, not a contract. If you find a better point or lose one, update the outline and the thesis so they still match. A quick reverse outline at the end catches anything you missed.
