The introduction is the paragraph students spend the longest on and readers judge the fastest. Instructors often decide within four sentences whether they are reading a focused essay or a wandering one, and they are usually right. That is not because introductions are magic; it is because the habits that produce a vague opening produce a vague essay.
Instead of listing rules, this guide takes one introduction through three drafts. The assignment: a 1,000-word argumentative essay answering “Should cities make public transit free to ride?” Each draft is shown in full, followed by what changed and why. By the end you will have a repeatable revision procedure, plus a set of hook options for other essay types.
The three jobs, briefly
An introduction is a funnel. It opens wide enough to invite a reader in and narrows to one precise claim.
- Hook: the first sentence or two. It earns attention by being specific, not by being dramatic.
- Context: two or three sentences that tell the reader what the issue is and why it is live right now.
- Thesis: one or two sentences stating what you will argue and, ideally, hinting at how.
Keep those three labels in mind. Every revision below is really a question of whether each sentence is doing one of those jobs or just taking up space.

Draft one: what most first drafts look like
Since the beginning of time, people have needed to get from one place to another. In today’s modern world, transportation is more important than ever. There are many different types of transportation, such as cars, buses, trains, and bicycles. Public transit is a very important topic that affects many people in cities all around the world. Some people think public transit should be free, while others disagree. In this essay, I will discuss the pros and cons of free public transit and give my opinion.
Six sentences, 88 words, and a reader learns nothing they did not already know. Take it sentence by sentence:
- “Since the beginning of time” could open an essay on any subject. It is filler that sounds like an opening.
- “In today’s modern world” is the same move with a different costume.
- Listing types of transportation is context, technically, but for a reader who has ridden a bus it explains nothing.
- “Very important topic that affects many people” asserts importance instead of showing it.
- “Some people think X, others disagree” is true of every debatable question and therefore says nothing about this one.
- “In this essay, I will discuss the pros and cons and give my opinion” announces the assignment rather than making a claim. The reader still does not know which side the writer takes.
The draft has a hook-shaped sentence, context-shaped sentences, and a thesis-shaped sentence, but none of them does its job. This is the most common introduction problem, and it is invisible to the writer because the paragraph looks complete.
Draft two: cut the filler, commit to a side
The first revision does two things: delete every sentence that could belong to any essay, and replace the announcement with an actual claim.
Every weekday morning, millions of commuters make the same small calculation: is the bus worth the fare today, or is it faster to drive? A handful of cities have removed that calculation entirely by making public transit free. Critics say the lost fare revenue is unaffordable. I believe free public transit is a good idea because it helps the environment and helps poor people.
Better. The opening now contains a specific scene from the topic (the daily fare calculation) rather than a statement about the history of movement. The context sentence tells the reader what is actually happening in the world. The critics get one sentence, which signals the essay knows an objection exists. And the last sentence takes a side.
What still fails:
- “I believe” and “is a good idea” are soft. The claim needs no announcement of belief; stating it is enough.
- “Helps the environment and helps poor people” names two reasons so vaguely that the body paragraphs have nothing to aim at. Which environmental effect? Helps poor people how?
- The critics’ objection is raised and then ignored. A thesis for an argumentative essay is stronger when it answers the objection it just mentioned.
Draft two would earn a “meets expectations” from most rubrics. The gap to “exceeds” is entirely in the last sentence. If your thesis is the part that keeps failing, How to Write a Thesis Statement That Holds the Essay Together works through that sentence in depth.
Draft three: sharpen the thesis until it predicts the essay
Every weekday morning, millions of commuters make the same small calculation: is the bus worth the fare today, or is it faster to drive? A handful of cities have removed that calculation entirely by making public transit free, and critics have answered with a predictable objection: the lost fare revenue is money the city cannot spare. That objection gets the accounting backward. Free transit is worth its cost because it eases the congestion that already costs cities far more than fares bring in, and because it reaches low-income riders whom targeted discount programs consistently miss.
Four sentences, 96 words, and now the paragraph does everything the three jobs require. Notice the specific changes from draft two:
- The critics’ objection is folded into the context sentence, so the thesis can answer it directly (“gets the accounting backward”).
- “I believe” is gone. The claim stands on its own.
- The two vague reasons became two specific mechanisms: congestion cost versus fare revenue, and discount programs missing the riders they target. Each is a body section waiting to be written.
- The paragraph is not shorter than draft two. Cutting filler freed space, and that space went to precision.
A reader who finishes draft three can predict the essay: a section on congestion economics, a section on who discounts miss, probably a paragraph conceding what free transit does not solve. That predictability is the point. An introduction is a promise, and a specific promise is easier to keep.
The revision procedure, extracted
You can run the same three passes on any introduction.
Pass one: the any-essay test. Read each sentence and ask whether it could open an essay on a different topic. If yes, cut it. This usually removes the first two or three sentences of a student draft and is the single highest-value edit available.
Pass two: the side test. Find the sentence that states your position. If it begins “In this essay I will,” “This paper discusses,” or “I believe,” rewrite it as a flat claim. If it lists reasons, check whether each reason is specific enough to become a paragraph.
Pass three: the prediction test. Hand the introduction to someone and ask them to guess the body paragraphs. If they cannot, the thesis is still too vague. If they guess paragraphs you do not intend to write, the thesis is promising the wrong essay.
Run pass three last and after the body is drafted. The thesis should describe the essay you actually wrote, not the one you planned. Reading the prompt carefully at the start helps too; How to Read an Essay Prompt Before You Write a Single Word covers how to make sure the claim answers the question that was actually asked.
Hooks that fit the essay type
Draft three opened with a scene because the essay is argumentative and the scene dramatizes the stakes. Other essay types call for other openings. The right hook is the one that already contains your topic.
| Essay type | Hook that works | Example opening (transit topic) |
|---|---|---|
| Argumentative | A concrete scene showing the tension | The morning fare calculation above |
| Expository / informational | A specific fact the reader probably does not know | One sourced figure about ridership or fare revenue in the city you are writing about, stated plainly in a single sentence |
| Compare and contrast | The two things placed side by side in one sentence | “Tallinn made its buses free in 2013; Paris chose to subsidize fares instead.” |
| Analytical | A definition the essay will complicate | “Free is never free; the question is who pays and whether they notice.” |
| Narrative / reflective | A moment in the middle of the action | “The driver waved me on without looking at the fare box, and I did not understand why until the next stop.” |
| Literary analysis | A short quotation from the text, immediately interpreted | Quote, then one sentence on what it sets up |
Openers to avoid regardless of type: dictionary definitions (“Webster’s defines transit as”), sweeping history (“throughout human history”), rhetorical questions with obvious answers (“Have you ever wanted to save money?”), and statistics you cannot source. The last one matters: an invented or half-remembered number in the first line undermines everything after it.
A length rule you can actually apply
Aim for about one-tenth of the total word count, with a floor of four sentences. That gives:
- 500-word essay: 50 to 70 words
- 1,000-word essay: about 100 words (draft three above is 96)
- 2,500-word paper: 200 to 250 words, sometimes as two paragraphs
An introduction that runs long is almost always doing one of two things it should not: summarizing the body in advance, or supplying background the reader does not need until later. Move both into the first body paragraph or cut them. If you are working from a five-paragraph plan, The 5-Paragraph Essay Outline shows how the introduction’s thesis maps onto the three body paragraphs, and How to Choose a Strong Topic for a Five-Paragraph Essay helps make sure the topic is narrow enough to introduce in a hundred words.
Common mistakes, each with a fix
- The throat-clearing opener. “In modern society,” “Since ancient times.” Delete and start with your topic’s first specific detail.
- The announcement thesis. “This essay will explore.” Replace with the claim itself.
- The both-sides shrug. “There are many opinions on this issue.” State yours.
- Reasons too vague to build on. “It has many benefits.” Name two, specifically enough that each could head a paragraph.
- Background overload. Three sentences of history before the reader knows what the question is. Cut to one, or move it to the body.
- A thesis that does not match the body. Fix the thesis, not the body, once the essay is drafted.
- A mystery opening. Withholding the topic for suspense works in fiction. In an essay it reads as confusion.
A final check before you move on
Read your introduction one more time and answer four questions honestly:
- Does the first sentence contain a detail that could only belong to this topic?
- Is there a sentence a reader could underline as the claim, with no “I will discuss” in front of it?
- Could someone guess the body paragraphs from the thesis alone?
- Is the paragraph within a tenth of the essay’s length?
Four yeses and the introduction is done. If any answer is no, you know which of the three passes to run again. Short, specific, and honest about what the essay will do beats long and impressive every time, and the reader trusts an essay that knows where it is going from the first line.
Frequently asked questions
What are the three parts of an essay introduction?
A hook that earns a few seconds of attention, two or three sentences of context that orient the reader and narrow the topic, and a thesis that states your specific claim. Think of it as a funnel from wide to narrow. When one part is missing the paragraph feels either abrupt (no context) or aimless (no thesis), and readers notice the gap even if they cannot name it.
How long should an essay introduction be?
Roughly one-tenth of the essay, with a floor of about four sentences. A 500-word essay gets a 50-to-70-word introduction; a 2,000-word paper can carry 150 to 200. If yours is much longer, you are probably summarizing the body in advance or explaining background the reader does not need yet. Move that material into the first body paragraph.
Should I write the introduction first or last?
Draft a rough version first so you have a working thesis, then rewrite it last. You cannot introduce an argument you have not yet made, and the thesis almost always shifts while you write the body. Students who polish the opening before the body exists end up with an introduction that promises a different essay than the one they delivered.
What is a good hook for an essay that is not a gimmick?
A specific fact from your topic, a short concrete scene, a definition the essay will complicate, or a pointed question the essay actually answers. The test is whether the hook could open any essay on any subject. “Since the beginning of time” and “Everyone has an opinion about” fail that test. A hook that already contains a detail from your topic passes.
