Than and then are two different English words with different meanings and jobs in a sentence. Than is mainly used for comparisons, while then usually refers to time, order, or what happens next. People often confuse them because they sound very similar in everyday speech, especially in fast conversation.
Their spelling differs by only one letter, which makes the mistake easy to make when writing. This guide explains the difference between than vs then, their origins, British and American usage, common mistakes, everyday examples, and simple ways to remember which word to use. By the end, the difference should be clear.
Quick Answer
The easiest rule is:
Than = comparison
Then = time or sequence
Use than when comparing two or more things.
- Sarah is taller than Mia.
- This book is better than the movie.
- I would rather walk than wait.
- He earns more than his brother.
Use then when talking about time or showing what happens next.
- We went home then.
- Finish your work, then call me.
- First, add the flour. Then, add the milk.
- I lived there then.
A quick memory trick is:
Than compares. Then follows time or order.
This distinction covers most everyday uses of the two words.
The Origin of Than vs Then
Although than and then look and sound similar, they have different histories and developed different meanings.
Than comes from Old English þanne and related forms. It became associated with comparison and eventually developed into the word used after comparative expressions.
For example:
taller than
faster than
more expensive than
Then also comes from Old English. It developed from an earlier word meaning something like “at that time” or “at that moment.”
Its connection with time remains clear today:
I was younger then.
Then also developed a meaning connected with sequence or next:
First we ate, then we left.
The spelling overlap exists because the two words have related historical forms. Over centuries, English spelling changed, while their meanings became more clearly separated.
Today, modern English treats than and then as separate words with different grammatical functions.
British English vs American English Spelling
There is no major spelling difference between British English and American English for than and then.
Both varieties use:
- than for comparisons
- then for time and sequence
| Meaning | British English | American English | Example |
|---|---|---|---|
| Comparison | than | than | She is older than me. |
| Time | then | then | I lived there then. |
| Sequence | then | then | Eat first, then leave. |
| Conditional result | then | then | If that is true, then we agree. |
Unlike colour/color or centre/center, there is no UK-US spelling choice here.
This means the same rule works whether you are writing for readers in London, New York, Toronto, Sydney, or an international audience.
The main challenge is not regional spelling. It is knowing whether your sentence expresses comparison or time/order.
Which Spelling Should You Use?
Choose than when your sentence compares people, objects, actions, amounts, or qualities.
Examples:
- My car is faster than yours.
- This test was easier than the last one.
- She works harder than I do.
Choose then when you mean a particular time or the next step.
Examples:
- I was living in Paris then.
- We had dinner and then watched a movie.
- Read the instructions, then begin.
This rule works in:
- American English
- British English
- Canadian English
- Australian English
- General international English
If you are writing professionally, choosing the correct word matters because confusing than and then can make otherwise clear writing look careless.
Common Mistakes with Than vs Then
The most common mistake is using then after a comparative word.
Incorrect:
My phone is newer then yours.
Correct:
My phone is newer than yours.
Another common mistake happens when describing a sequence.
Incorrect:
First, we had lunch than we went shopping.
Correct:
First, we had lunch then we went shopping.
Here are more examples:
| Incorrect | Correct | Why? |
|---|---|---|
| She is taller then me. | She is taller than me. | Comparison |
| I would rather stay than leave. | I would rather stay than leave. | Comparison |
| First study, than take the test. | First study, then take the test. | Sequence |
| We went home and than slept. | We went home and then slept. | Sequence |
| He was younger than. | He was younger then. | Refers to past time |
| If you agree, than we can start. | If you agree, then we can start. | Result/sequence |
A simple test can help: if you can replace the word with compared with, use than. If you can replace it with next, after that, or at that time, use then.
