Then is a word that helps us talk about time and sequences, showing when something happens or what comes next.

When you use then to mark time, you're pointing to a specific moment: “Back then, people didn't have smartphones” or “I'll finish my homework, and then I can play outside.” It creates a clear before and after.

Then also shows cause and effect, connecting an action to what logically follows: “If you study hard, then you'll do well on the test.” This use helps explain how one thing leads to another.

You'll sometimes hear people say “now and then” to mean occasionally, or “then again” when they're about to present another side of an argument. When someone says “but then,” they're usually about to add a complication or new consideration to what they just said.

Be careful not to confuse then with than, which is used for comparisons: “I'd rather read than watch TV.” An easy way to remember: then is about time (both have an 'e'), while than is for comparing things.
