If you often pause when writing than vs then, you are not alone. These two words look and sound similar, but they have completely different jobs in a sentence. Than is mainly used when you compare two or more things. Then usually tells us about time, order, or what happens next. For example, you might say, “My car is faster than yours,” but “I finished work, then I went home.”
The confusion is common because the words differ by only one letter and can sound similar in fast speech. Both American and British English use than and then in the same basic ways. There is no major UK vs US English grammar difference in their meanings or correct usage.
Understanding the than vs then grammar difference is useful in school, business writing, emails, social media, and everyday conversation. Once you learn the simple rule, choosing the right word becomes much easier.
Quick Answer
Here is the easiest way to remember the difference:
| Word | Correct use | Example |
|---|---|---|
| Than ✓ | Used for comparisons | Sarah is taller than Mia. |
| Then ✓ | Used for time, order, or results | We ate dinner, then watched a movie. |
| Than ✗ | Wrong when you mean “next” or “after that” | I went home than I slept. |
| Then ✗ | Wrong when making a comparison | She is older then me. |
Simple rule:
Than = comparison
Then = time or sequence
A useful memory sentence is:
Better than something, and then something happens.
What Does Than Mean?

It often appears after comparative words such as:
- better
- bigger
- smaller
- faster

Than in American English
Here are common American English examples:

British English uses than in the same way:
- London is larger than many British cities.
- This book is better than the first one.
- Your new office is closer than mine.
- The train was later than expected.
- He is younger than his sister.
There is no meaningful difference here between American and British English.
What Does Then Mean?
Then is mainly an adverb. It can describe a time, an order of events, or a result.
It can mean:
- at that time
- next
- afterward
- in that case
- as a result
For example:
- I was living in Chicago then.
- First, wash the vegetables. Then cut them.
- We had dinner and then went home.
- If you are tired, then you should rest.
- Finish your homework, then you can play.
Then in American English
- I finished my report and then sent it.
- Back then, I lived with my parents.
- First, call the bank. Then check your account.
- We can talk then.
- If that is true, then we need another plan.
Then in British English
- We had tea and then went for a walk.
- I lived in Manchester then.
- First, take the train. Then change at Leeds.
- We can discuss it then.
- If you agree, then we can continue.
Again, the basic correct usage is the same in both varieties of English.

Why Do People Confuse Than and Then?
There are several reasons.
First, the words look almost identical. The only difference is the letter a and e.
Second, their pronunciation can become less distinct in quick conversation.
Third, autocorrect and casual texting can make mistakes easy to miss.
Fourth, many learners memorize the words without learning their grammatical roles.
The best solution is not to memorize spelling alone. Learn what each word does.
If you are comparing, choose than.
If you are talking about time, order, or a result, choose then.
Pronunciation Guide
The standard pronunciations are:
| Word | IPA | Simple pronunciation |
|---|---|---|
| than | /ðæn/ | th-an |
| then | /ðen/ | th-en |
Both begin with the voiced th sound /ð/, as in this and that.
The vowel is different:
- than has the /æ/ sound, similar to the vowel in cat
- then has the /e/ sound, similar to the vowel in bed
In natural speech, especially in fast conversation, these sounds can become less noticeable. This is one reason the words are frequently confused in writing.
Word Origins and Etymology
Although than and then look closely related, their histories are different.
Than comes from Old English forms such as þanne and þan, which were connected with comparison. Over time, the word developed into the modern English than.
Then also comes from Old English. It developed from forms such as þanne and þonne, which referred to time or a particular point in sequence.
Their historical forms were similar, which helps explain why modern learners may find them confusing. However, their modern meanings have become clearly separated.
Than vs Then Synonyms
The words do not have exact synonyms in every sentence. However, some alternatives can help you understand their meanings.
| Word | Possible alternative | Example |
|---|---|---|
| Than | compared with | She is taller than me. |
| Than | in comparison with | It is cheaper than the other one. |
| Then | next | We ate, then left. |
| Then | afterward | We left afterward. |
| Then | later | I will call you later. |
| Then | at that time | I lived there then. |
In both American and British English, than is normally preferred for direct comparisons. Then is normally preferred for sequence and time.
