A marker reads your introduction twice. First before they know what you are arguing, and then again once they have finished the essay — and the second read is the revealing one. If the opening promised one thing and the body delivered another, the whole piece feels unsteady, however strong the analysis is. A first-class introduction is not decoration. It is a contract with your reader, and it can be learned.

What an introduction actually has to do

Strip away the nerves and an introduction has three jobs. It orients the reader in the debate, it shows you have understood the question rather than a neighbouring one, and it states the line of argument the rest of the essay will defend. Everything else — the hook, the context, the roadmap — exists to serve those three things.

A useful test: cover the body of your essay and read only the introduction. Could a marker predict what you will argue, and roughly how you will get there? If not, the opening is doing too little. If they could write the essay themselves from it, it is doing too much.

Step one: open with a hook that earns its place

A hook should create a small piece of pressure that the essay then releases. That usually means a tension, a surprising contrast or a question the reader cannot answer immediately. Avoid grand openings ("Since the beginning of time, humans have…") and dictionary definitions. Both signal a student filling space before the real work begins.

Take a title such as To what extent is social media responsible for declining trust in journalism? Compare two openings:

• Weak: "Social media is a topic that has been discussed a great deal in recent years."
• Stronger: "Ask a newsroom what damaged public trust most and few would name the printing press. Most would point to the share button."

The second version proves nothing yet, and it does not need to. What it does is set up a claim about cause and blame that the rest of the essay can test, qualify or reject.

Step two: build context that narrows rather than sprawls

Context works like a funnel. Two or three sentences should carry the reader from the broad area to your specific question, and every sentence should move them closer to it. If a sentence could sit in an essay on a different title without change, cut it.

This is where most weak introductions fail: three paragraphs of module history, a potted biography of a theorist, or a summary of a lecture, none of which the argument needs. Background is not the same as context. Context is the minimum the reader must know to see why your question matters.

Define the terms that carry weight

If the question hinges on a contested term — fairness, development, the rule of law, sustainability — say in one sentence how you will use it. A brief working definition is far more useful than a quoted dictionary entry, and it protects you from a marker who reads the term differently.

Step three: commit to a thesis

The difference between a thesis and a statement of intent is direction. "This essay will explore the role of social media in public trust" tells the reader nothing they did not already know from the title. A thesis takes a position and gives a reason for it:

This essay argues that social media has eroded trust in journalism less by spreading falsehood than by making the audience for news visible, and therefore contestable, in ways broadcast media never did.

Notice what that sentence is doing. It answers the question, it commits to a mechanism, and it leaves room for a counter-argument. A reliable pattern is X, because Y, although Z — the "although" clause shows the marker you are aware of the strongest objection rather than hoping they will not notice it.

A thesis may be qualified; it must not be timid. "This essay will consider several perspectives" is not an argument. If nobody could reasonably disagree with your claim, you have written a description.

Step four: signpost the route, briefly

One or two sentences are enough. "The essay first examines how trust is measured, then turns to platform design, and concludes by weighing the evidence against the newsroom's own choices." That is a map, not a list of chores.

Avoid four consecutive sentences beginning "Firstly… Secondly… Thirdly…", which reads like a contents page. Also check that your signposted order matches the order of the paragraphs you actually write — a mismatch is one of the quickest ways to lose structure marks, because the marker is reading for a route you never take.

Common mistakes that hold an introduction back

• Background bloat. Context that runs past a short paragraph before any claim appears.
• Announcing instead of arguing. "This essay aims to look at…" is a weather forecast, not a position.
• The dropped quotation. A striking line in the opening that is never mentioned again.
• Question drift. Answering "how far" with "what", or "why" with "whether".
• Over-length. If your introduction runs much past a tenth of the word count, you are probably saying something twice.

Before you write the next paragraph: a five-minute check

Run these checks after drafting, and again after you have finished the essay:

1. Read the title aloud, then read your thesis. Does one answer the other directly?
2. Underline your argument sentence. If you cannot find it, write it now — everything else follows from it.
3. Delete any sentence that could appear in an essay on a different title.
4. Confirm that your signpost matches the order of your sections.
5. Read the whole introduction out loud. Wherever you stumble, the reader will stumble too.

Get this right and the rest of the essay becomes easier, because the hardest decision — what you are actually arguing — has already been made. Some writers draft the introduction last; others polish it first and build towards it. Both work. What matters is that by the time a marker reaches the second read, the contract is clear and the essay keeps it.
