I fixed an error in a client’s document recently. They had written compliment when the context of the sentence seemed to indicate complement. It was a perfect topic for another difference between post.
Compliment is a remark that says something positive about someone or something. Complement, on the other hand, refers to something that helps to complete something else.
Examples:
- Telling me I am handsome is a compliment.
- Hot peppers are a good complement to great nachos.
