A good introduction does three jobs: it hooks the reader, gives just enough context, and states where the piece is going. Get those three right and the reader commits to the rest. Get them wrong and even strong writing underneath goes unread.
The three-part structure
- The hook (1–2 sentences). Open with something that earns attention — a surprising fact, a sharp question, a vivid example, or a clear stake. Skip the throat-clearing (“Since the dawn of time…”).
- The bridge (2–3 sentences). Give the context the reader needs to understand why this matters now — and no more. This is where you narrow from the hook toward your specific point.
- The thesis (1 sentence). State your main claim or what the piece will deliver. For essays this is your argument; for an article it’s the promise you’re making to the reader. See our guide to thesis statements.
Write it last
Here’s the trick most people miss: write the introduction after the body. You can’t introduce a piece you haven’t written yet. Draft a rough placeholder, write everything else, then come back and write the real opening once you know exactly what you’re introducing.
Match the hook to the format
An academic essay opens differently from a blog post. Academic: lead with the problem and its significance. Blog or email: lead with the reader’s pain or curiosity. When you’ve drafted an opening but the register feels off, run it through the paraphraser — Formal for academic work, Casual or Fluent for a friendlier piece.
Common mistakes
- Burying the point so deep the reader gives up first.
- Over-explaining — front-loading background nobody asked for.
- A hook that doesn’t connect to what follows.
Polish the first impression
Your opening lines get read the most and forgiven the least, so finish them carefully: run the grammar checker and check the readability so the very first sentence is effortless to read. A clean, confident open buys you the whole piece.
