Introduction Paragraph Examples: Samples and Writing Guide

An introduction paragraph is the first paragraph of an essay, where the writer earns the reader's attention with a hook, frames the topic with one to three sentences of context, and commits to a thesis the rest of the essay will defend. Strong introductions perform all three jobs in 80 to 200 words; weak introductions either skip a job, repeat themselves, or land on a thesis the body cannot support. EssayFount writing experts coach introduction paragraphs across argumentative, narrative, research, business, and admissions essays, where the first paragraph carries disproportionate weight in graders' early impressions.

What an Introduction Paragraph Has to Do

The introduction paragraph performs three jobs in roughly this order: earn attention, frame the topic, and commit to a position. Writers who try to add a fourth job (forecasting the body in detail, defining every key term, hedging against counterarguments) usually overload the paragraph and bury the thesis.

Job 1: Earn Attention With a Hook

The first sentence or two earn the reader's attention before the essay arrives at the topic. Effective hooks are specific: a concrete anecdote, a surprising statistic, a sharp question, a direct claim, a vivid scene, a strong quotation, or a defining image. Generic hooks ("Throughout history, people have always...") signal a writer who has not committed to a specific angle.

Job 2: Frame the Topic

After the hook, two to four sentences move from the hook into the topic and provide whatever background the reader needs to understand the thesis. The framing answers questions such as: what is at stake, when is this happening, who is affected, what previous thinking on this topic should the reader know.

Job 3: Commit to a Thesis

The final sentence states the central claim and (in shorter essays) previews the reasons or moves the body will defend. A strong thesis is arguable (someone could disagree), specific (it makes a precise rather than a vague claim), and structured (it forecasts the body of the essay).

Introduction Paragraph Structure

The structure has six functional moves. Not every introduction uses all six; the moves required depend on the essay length and type.

1. Hook (1-2 sentences): earn attention.
2. Bridge (1 sentence, optional): connect the hook to the topic.
3. Background (1-3 sentences): orient the reader to the topic.
4. Stakes (1 sentence, optional): explain why the topic matters.
5. Thesis (1 sentence): state the central claim.
6. Forecast (1 sentence, optional): preview the body's main moves.

For five-paragraph essays, the structure is typically hook + background + thesis (the bridge, stakes, and forecast are folded into the thesis). For long-form research papers, the introduction may run several paragraphs, with the structure expanded across them.

Introduction Paragraph Examples by Essay Type

Argumentative Essay Introduction

Argumentative introductions favor direct claims and surprising statistics in the hook position. The thesis should be unambiguous and contestable.

Sample (Topic: Federal Minimum Wage)

The average American worker spends about a third of their gross pay on
housing, but for the lowest-paid quintile that figure is closer to half.
Federal minimum wage policy has not kept pace with that rent burden for
more than fifteen years; the federal floor of USD 7.25, last raised in
2009, now sits below the 1968 minimum in real terms. Economists,
employers, and policymakers have offered three competing theories about
what an updated federal floor would do to employment, prices, and small
businesses. The case for raising the federal minimum wage to USD 17 by
2028 rests on the same three findings the empirical literature now
supports: that price-pass-through is smaller than its critics claim,
that small-business closure rates are driven more by rents than by
wages, and that wage compression disappears within two years of the
increase.

Annotation

The hook is a surprising statistic (housing burden differential by quintile). The framing places the topic in historical context (last raised 2009, below 1968 in real terms) and signals the existing debate. The thesis previews the three reasons the body will defend, in the order it will defend them.

Literary Analysis Introduction

Literary introductions favor strong quotations and close-reading hooks. The thesis should commit to a specific reading of the text.

Sample (Topic: The Great Gatsby)

"It eluded us then, but that's no matter, tomorrow we will run faster,
stretch out our arms farther." Fitzgerald's closing line names the
tension that drives every page of The Great Gatsby: a future
that can only be reached by re-entering a past that no longer exists.
The novel watches Gatsby build a fortune, a mansion, and a public
identity to recover one summer with Daisy Buchanan, and the reader is
asked to decide whether that pursuit honors human aspiration or empties
it. Gatsby's pursuit of the past is ultimately self-destructive because
it forces him to misread Daisy as a symbol rather than a person, to
compress five years of her life into a moment he can repossess, and to
refuse the present that might have offered him a different and more
achievable future.

Annotation

The hook is a strong quotation that the essay will return to. The framing names the central tension (recovering an irrecoverable past) and the question the novel asks the reader. The thesis previews three reasons (misreads Daisy, compresses time, refuses present) in body-paragraph order.

Personal or Admissions Essay Introduction

Personal essay introductions favor specific anecdotes and vivid scenes. The "thesis" is often implicit rather than stated; the reader should be able to articulate the essay's takeaway by the end without having been told it directly.

Sample (Topic: Personal Growth, College Admissions)

The morning I admitted to my chemistry teacher that I had memorized the
periodic table during a hospital stay, her first response was to ask
which element I had stopped on. I said selenium because I had stopped
on selenium. She said good, and pulled out a pen and the back of an
attendance sheet, and we drew the rest of the table out together until
the bell.

Annotation

This is a single-paragraph introduction that compresses hook and framing into a scene. The thesis is implicit: the essay will be about specificity, about the difference between knowing something and using it, about the teacher who taught the writer that difference. Personal essays often defer the explicit thesis until the body or even the conclusion.

research paper writing guide Introduction

Research paper introductions are usually 2 to 4 paragraphs in length and follow a standard sequence: broad context, narrowing focus, gap or problem, research question, contribution.

Sample (First Paragraph of a Multi-Paragraph Introduction)

Workplace reading has become a contested category in organizational
research over the past decade. Studies of professional reading from
2015 to 2020 documented widespread skim-reading of internal
communications and identified its consequences for decision quality
(Bennett 2018; Whitfield 2020), but the field's empirical methods have
relied almost exclusively on self-reported survey data. The question of
what predicts an engagement decision (whether and how carefully a
worker reads a given document) remains underdetermined because
self-reports correlate poorly with the diary studies and screen-capture
data that newer methodologies make available. This paper addresses that
gap by analyzing diary data from 42 mid-career professionals, paired
with a one-week screen-capture sample, to identify the cues that
predict careful reading. The contribution is twofold: a method for
combining diary and capture data and a finding that organizational
signals (who circulated the document, who is copied) outweigh content
cues.

Annotation

The opening sentence places the topic in the field's recent literature. The middle sentences identify the gap (self-report data dominates, but methodologies are improving). The thesis sentence is the final one: a statement of the contribution. Research papers rarely use the kinds of attention-grabbing hooks that work in shorter essays; the hook in a research paper is the freshness of the question.

Compare-and-Contrast Essay Introduction

Compare-and-contrast introductions name both subjects and signal the basis of comparison.

Sample (Topic: Two Cities)

Boston and San Francisco are both nineteenth-century port cities that
became twenty-first-century technology hubs, both with universities
older than the cities that grew up around them, and both now grappling
with housing crises their booms produced. The cities also differ in
ways their similar trajectories obscure. This essay compares Boston
and San Francisco on three dimensions where their differences matter
most for residents: the structure of their housing markets, the design
of their public transit, and the relationship between local government
and the technology industry. The comparison shows that what looks like
a shared challenge is actually two different challenges with different
political and economic logics.

Annotation

The hook places both subjects on the table and notes the surface similarity. The framing acknowledges the differences the essay will explore. The thesis names the three dimensions of comparison and previews the conclusion.

Five-Paragraph Essay Introduction (Compressed)

Five-paragraph introductions compress the structure into 80 to 120 words. The hook is one or two sentences, framing is one or two sentences, and the thesis is the final sentence with a clear three-part forecast.

Sample (Topic: School Start Times)

American teenagers wake up earlier than astronauts on the International
Space Station and twice as early as their grandparents did at the same
age. Most U.S. high schools start before 8:00 a.m., a schedule American
sleep researchers now agree is incompatible with adolescent biology.
High schools should start at 8:30 a.m. or later because the schedule
improves measurable academic performance, reduces traffic accidents
involving teen drivers, and supports adolescent mental health.

Annotation

The hook is a comparative statistic (vs. astronauts and grandparents). The framing names the school-start-time problem in one sentence. The thesis commits to the position and forecasts three reasons (academic performance, traffic safety, mental health). The whole introduction lands in roughly 90 words.

AP and Standardized Test Essay Introduction

Timed-essay introductions compress further: 60 to 90 words, two to three sentences. The opening hook is usually a direct claim; the thesis arrives by the second or third sentence.

Sample (Topic: AP English Language Free-Response)

Roosevelt's 1936 address argues that the American economy in 1936 is
neither the economy of 1920 nor the economy that the speech's audience
fears it has become. Roosevelt establishes that argument through three
rhetorical moves: a concrete inventory of what has changed, a contrast
between rumor and data, and a call to action that treats the changes
as the audience's collective work rather than the government's alone.

Annotation

The hook is a direct claim about the speech's central argument. The thesis (the second sentence) forecasts the three rhetorical moves the body will analyze. Timed essays rarely have time for elaborate framing; commit fast and analyze in the body.

Common Introduction Paragraph Mistakes

• "Throughout history" or "In today's society" openings. Generic, abstract, and unfalsifiable. They signal a writer who has not committed to a specific angle.
• Dictionary definitions. "Webster's dictionary defines..." has not been fresh since the 1990s. Define a term in your own voice when definition is needed.
• Famous-person quotations as decoration. Opening with a famous quotation that has nothing to do with the body of the essay reads as performance. Quote only when the quotation does work.
• Thesis as the first sentence. Front-loading the thesis eliminates the framing that lets the reader understand why the thesis matters. The thesis belongs at the end of the introduction, not the beginning.
• Vague thesis. "There are many reasons why..." is not a thesis. A thesis must commit to one specific claim.
• Thesis that is too broad. "Climate change is bad" cannot be defended in 800 words. Narrow the scope to one specific claim about climate change.
• Multi-sentence thesis. The thesis should be one sentence. Multi-sentence theses usually mean the writer has multiple arguments compressed together; pick one.
• Five-paragraph thesis with no forecast. Short essays benefit from a thesis that previews the three reasons the body will defend. Skipping the forecast forces the reader to wait for structure.
• Long-form thesis with too much forecast. Long essays should not list ten body sections in the thesis sentence. Forecast at the macro level (the contribution) and let the body develop the moves.
• Bridge sentence that announces the essay. "In this essay, I will discuss..." is filler. The thesis should commit to a position rather than describe what is about to happen.
• Background that goes too far back. Starting an essay on 2024 climate policy with the Industrial Revolution wastes 60 percent of the introduction on context the reader does not need.
• Background that is missing entirely. Hook + thesis with no framing leaves the reader unable to evaluate why the thesis matters. Two to three sentences of context are nearly always required.
• Hook and thesis pulling in different directions. An anecdote about the importance of failure followed by a thesis arguing for risk avoidance reads as two different essays. The hook should set up the thesis.
• Repeating the prompt verbatim. Beginning with "The prompt asks me to discuss..." wastes the hook. Engage the topic without restating the assignment.

How to Draft an Introduction Paragraph

1. Draft the thesis first. The introduction's job is to set up the thesis; you cannot write the introduction until you know what it leads to.
2. Write the hook last. Many writers spend disproportionate time on the opening sentence. Draft the body of the essay first; the hook will reveal itself from material you have already written.
3. Test the framing for length. Two to four sentences of context is the right range for most essays. More than four usually means the framing is doing the body's job.
4. Read the introduction aloud. Strong introductions land at conversational speed. Stumbles signal sentences trying to do too many jobs at once; break those into two sentences.
5. Cut the first sentence. Many drafts begin with a "warm-up" sentence before the hook arrives. Read with the first sentence deleted; if the second is stronger, cut the first.
6. Confirm the thesis matches the body. Drafts that change direction during the body usually end with introductions that no longer fit. Re-read the introduction after the body is final and revise to match.
7. Verify the forecast. If the thesis previews three reasons, confirm those three reasons are the actual body paragraphs in the right order.
8. Check the register. A casual hook on a formal essay (or vice versa) reads as two essays. Match tone across the introduction and body.

How EssayFount Writers Approach Introductions

EssayFount treats the introduction paragraph as a structural unit rather than a stylistic flourish. The internal workflow drafts the thesis first, the body second, and the introduction third (or sometimes second-to-last, after the conclusion has clarified what the body actually argued). Hooks are workshopped against three to four candidate openings to make sure the chosen one is specific, in the writer's voice, and connected to the actual argument.

For admissions, scholarship, and personal essays, EssayFount writers default to the specific anecdote or vivid scene. For argumentative and academic essays, the direct claim, surprising statistic, or strong quotation match the genre most cleanly. Matching hook type to essay type is most of what separates a strong introduction from a generic one.
