Compliment vs. Complement: What's the Difference?

Quick answer

  • A compliment is a kind remark, praise.
  • A complement is something that completes or improves another thing.

The difference

They sound identical, so only spelling separates them. Compliment is about words of praise; complement is about a good fit, two things that work better together.

When to use compliment

Use compliment whenever kind words are being given or received.

When to use complement

Use complement when two things fit together, or for a full set (a full complement of staff).

Remember it

ComplIment = I like it. ComplEment = it completes.

The e in complement matches the e in complete.
