Than vs. Then

The English words than and then look and sound a lot alike, but they are completely different. Here's how you can easily identify the difference between the two and begin to use them properly.

 

Than: a conjunction used in comparisons:

Examples:

Tom is smarter than Bill.

This is more important than you might think.

Is she taller than you?

Yes, she is taller than I.

 
Then: has numerous meanings.

1. At that point in time

I wasn't ready then.

Will you be home at noon? I'll call you then.

2. Next, afterward

I went to the store, and then to the bank

Do your homework and then go to bed

3. In addition, also, on top of that

He told me he was leaving, and then that I owed him money

It cost $5,000, and then there's tax too

4. In that case, therefore (often with "if")

If you want to go, then you'll have to finish your homework.

I'm hungry!
Then you should eat.

 
The Bottom Line is that than is used only in comparisons, so if you're comparing something use than. If not, then you have to use then. What could be easier than that?
