How to write an introduction

The introduction has two jobs: tell the reader what the piece is about, and give them a reason to keep going. It is not the place to show off or to start far back in history.

What it is

The introduction is the opening of a piece. It usually has three parts: an opening line that draws attention, a few lines of context that define the subject, and a statement of what the piece will cover (often the main point or a promise).

Why it matters

Readers decide within seconds whether to continue. A strong introduction earns the rest of the piece; a weak one loses the reader even if the body is excellent.

Step-by-step guide

Start with the specific, not the general. Begin with a striking fact, a concrete moment, a question, or a short scene — not "Since the beginning of time."

Keep the first line short. A short opening sentence is punchy and easy to read.

Define the subject quickly. Tell the reader what this piece is about and why it matters to them. Do not make them guess.

State the main point or the plan. In non-fiction especially, a clear "this piece explains/argues/shows X" helps the reader settle in.

Give a reason to care. Connect the subject to something the reader already knows or wants. "Why does this matter to you?"

Keep it brief. A few sentences is usually enough for an article or essay. Longer pieces can afford more setup; shorter pieces should be quick.

Hook and promise. The hook earns the click; the promise keeps them reading. Both belong in the introduction.

Common mistakes

Starting with a dictionary definition or "In today's world." Beginning too far back in time. Filling the introduction with questions. Giving away so much that the body has nothing left. Making it so long the reader never reaches the content.

Practical tips

• Write the introduction last, once you know what the piece actually became.
• Give the reader a single clear promise you will keep.
• Be concrete: a number, a name, or a moment beats a general statement.
• Do not save your best line for later; it may belong at the start.

Checklist

• My first line is short and specific.
• I defined what the piece is about early.
• I stated the main point or a promise.
• I gave the reader a reason to care.
• I kept it brief.
• I wrote it (or checked it) after the body was done.
