Many people mix up than and then because the two words look very similar. They differ by only one letter, and when speaking quickly, they can sound alike.
Students, English learners, and even native speakers sometimes use the wrong one in writing. The good news is that the difference is actually very simple once you understand what each word does.
A quick way to remember:
- Than is usually used for comparison.
- Then is usually used for time or order.
Once you learn this basic rule, choosing the correct word becomes much easier.
Quick Answer
Here is the simplest explanation:
Use than when comparing things.
Examples:
- My car is faster than yours.
- She is taller than her brother.
- I would rather read than watch TV.
Use then when talking about time or what happens next.
Examples:
- We ate dinner and then watched a movie.
- Finish your homework, then go outside.
- Back then, life was different.
Easy memory trick:
- Than = Comparison
- Then = Time or Next Step
Simple Origin or Background Explanation
Both words come from very old forms of English and have been used for hundreds of years.
In earlier English, the meanings were closer together than they are today. Over time, the language changed and each word developed a more specific job.
Today:
- Than mainly helps compare things.
- Then mainly shows time, order, or sequence.
Even though their histories are connected, modern English treats them as two different words with different uses.
Clear Explanation of the Difference
The easiest way to understand the difference is to look at each word separately.
What Does “Than” Mean?
Than is used when comparing two or more people, things, ideas, or actions.
Think of it as a comparison word.
Examples:
- Cats are quieter than dogs.
- This book is more interesting than that one.
- He works harder than I do.
- Summer is hotter than winter.
In each sentence, two things are being compared.
What Does “Then” Mean?

- Back then, smartphones did not exist.
In each sentence, then shows when something happened or what happened next.
