The good news is that the rule is simple once you understand it.
By the end of this guide, you’ll know exactly when to use each word. You’ll see clear examples, learn easy memory tricks, avoid common mistakes, and gain the confidence to use then and than correctly every time.

The Origin / Background of Then vs Than
These two words have been confusing writers for centuries.
Both come from Old English and were once more closely related than they are today. Over time, English evolved and the meanings became separate.
Then
