How to Write an Introduction Paragraph for an Essay (Examples)

Written & checked by Rabail, a student.

Quick answer: A strong essay introduction does four jobs in four sentences: a specific hook, one line of context, one line naming the tension in the question, and a thesis that states your answer and hints at your structure. Keep it to about 60-90 words. Plan first, then write it, and never open with "Since the dawn of time".

For about two years my introductions said nothing for six lines. My worst habit was the historical throat-clear, "Throughout history, people have always wondered", and my history teacher eventually wrote the same comment on three essays in a row: "Start marking here", with an arrow pointing at paragraph two. She meant my opening was doing zero work. Once I rebuilt how I open essays for IGCSE English Literature and A-Level History, my introductions got shorter and my marks went up. A tight introduction forces you to decide your argument before you start writing it.

What examiners actually reward in an introduction

They reward one thing above all: visible evidence that you are answering the question. Almost no mark scheme has a box labelled "introduction". What they do reward is a sustained, focused line of reasoning, and the introduction is where the examiner forms a first opinion about whether you have one.

  • Cambridge IGCSE and International A-Level literature papers credit a sustained personal response, so your reading of the text should be visible in the first three lines.
  • AQA, Edexcel and OCR GCSE English bands use words like "convincing" and "critical". A hedging opening reads as unconvincing before you have analysed anything.
  • AP free-response essays award a thesis point on its own, usually earned in the opening paragraph, and it must be a defensible claim rather than a restatement of the prompt.
  • CBSE Class 10 and Class 12 English answer writing is marked partly on relevance and organisation, so a wandering opening loses content marks directly.
  • WAEC and WASSCE English essays split marks across content, organisation, expression and mechanics. Organisation is judged from line one.

Five systems, one message: the examiner decides early whether you are answering or warming up.

The four moves, with actual word counts

  • Move 1, hook, 10-20 words. One concrete fact, date, number or image. Concrete always beats grand.
  • Move 2, context, 15-20 words. Where and when, or which text and which idea. Only what a reader needs to understand the tension coming next.
  • Move 3, tension, 10-20 words. The genuine disagreement inside the question. Why is this worth asking?
  • Move 4, thesis, 20-30 words. Your answer, plus a hint of the route you will take through it.

Total, 55-90 words. In a timed exam I aim for around 70. Past 100 words you are writing an essay before the essay.

A worked rewrite, line by line

Question: "To what extent was the Treaty of Versailles responsible for German instability in the 1920s?"

Here is the weak version, and I have written ones exactly like it:

"The Treaty of Versailles was a very important treaty signed after the First World War. It had many effects on Germany, both good and bad. Historians have debated this topic for many years. In this essay I will discuss the causes of German instability in the 1920s."

That is 47 words and it scores nothing. Sentence one states a fact nobody disputes, sentence two hedges in both directions at once, sentence three is filler, and sentence four announces rather than argues. "In this essay I will discuss" tells the examiner you have not decided your answer yet.

Now the rebuild, 73 words:

"By November 1923 a loaf of bread in Berlin cost 200 billion marks. Germany had signed the Treaty of Versailles four years earlier, accepting 132 billion gold marks in reparations and heavy territorial losses. Whether the treaty caused that chaos or merely deepened it is still contested. Versailles was the decisive trigger for Germany's economic instability, but its political instability grew from the fragility of the Weimar constitution rather than from the treaty."

Look at what the last sentence does. It takes a side, it answers "to what extent" by splitting the response into economic and political strands, and it hands you your essay structure for free. You never need to write "firstly" or "secondly", because the strands are already named.

Test your own attempt by pasting it into the essay coach and asking what argument it thinks you are about to make. If the answer comes back vague, your examiner will be vague about your marks too.

Match your opening move to the question stem

Different command words need different first sentences, and this is the part almost nobody teaches.

  • "To what extent" needs a measuring word in your thesis: largely, only partly, decisively in the short term. Examiners want degree, not just direction.
  • "Explain how" or "Explain why" does not want a debate hook at all. Open with the mechanism and name the two or three factors you will explain.
  • "Compare" needs both items and the basis of comparison inside sentence one. Do not spend the opening summarising one side.
  • "How does the writer present" wants the effect on the reader first, then the methods you will trace through the text.
  • "Discuss" or "Evaluate" wants both sides signalled, then a clear landing. Signalling both sides and never landing is the commonest way students miss the top band.

How long to spend, with real timings

For a 45-minute essay I use 5 minutes planning, 90 seconds on the introduction, 32 minutes on the body, 4 minutes on the conclusion, and whatever is left checking.

I timed this properly. Writing an introduction cold took me close to four minutes and it was still bad, because I was thinking and writing at once. After a five-minute plan it took 90 seconds and came out sharper, because the thesis was already on the plan in note form. Planning is what makes the introduction cheap to write.

For coursework the rule flips: draft the body first and write the introduction last, once you know what you actually argued. My first-draft thesis and my final thesis are almost never the same sentence.

Seven openers that quietly cost marks

Each has a direct swap.

  1. "Since the dawn of time" becomes a specific year or dated fact.
  2. "The dictionary defines X as" becomes your own one-clause definition, and only if the term is genuinely contested.
  3. "This essay will discuss" becomes the claim itself, stated flat.
  4. "There are many factors" becomes naming the factors.
  5. "X is a very important topic" becomes why it matters, with a number or example attached.
  6. Restating the question word for word becomes rephrasing it as your tension sentence.
  7. A famous quotation from outside the text becomes a short quotation from inside it, and only if you analyse it later.

To see how these read to a marker, run a full essay through the grader and read only the comments on your first paragraph.

Test yourself

  1. In a "to what extent" essay, which single word type must appear in your thesis, and why?
  2. Your introduction is 140 words long. Name two of the four moves most likely to be bloated.
  3. Rewrite this as a tension sentence: "Macbeth is a play about ambition."

FAQ

How long should an essay introduction be?

Between 55 and 90 words in a timed exam, which is usually four sentences. Coursework introductions can stretch to about 120 words because you have room for real context. Past 150 words in an exam you are stealing minutes from the analysis paragraphs, where the marks live.

Should I write the introduction first or last?

In a timed exam, write it immediately after your five-minute plan, because the plan already contains your thesis. In coursework, write it last, once the body has told you what you really argued. Rewriting the introduction at the end is normal, not a sign you planned badly.

Do I need a hook in an exam essay?

Yes, but a small one. A single concrete fact, date or image is enough, and it must connect to your argument. Skip it entirely for "explain how" questions, where the examiner wants the mechanism straight away.

Can I use "I" in an essay introduction?

In GCSE, IGCSE and A-Level English Literature, yes, sparingly, because a personal response is credited. For history and most AP free-response essays, state the argument directly without "I think", which reads as stronger anyway. Check the phrasing your own teacher marks with.

In short: an introduction is not a warm-up, it is the moment the examiner decides whether you have an argument. Four sentences, roughly 70 words, hook, context, tension, thesis. Plan it, write it fast, and spend the time you save on the paragraphs that carry the marks. For the rest of the essay, the English hub and the history hub have full walkthroughs.
