"Compliment" and "complement" are two words that sound the same but have very different meanings. They trip up even the best writers, but once you learn the difference, your writing will be much clearer and more professional.

The Basic Difference

Here's the simple distinction:

• Compliment is about praise.
• Complement is about completion.

Compliment: The Art of Praise

A compliment is a nice thing you say to someone. It's all about expressing admiration or appreciation.

How to Use "Compliment"

As a noun (the praise itself):

• She received a lot of compliments on her new haircut.
• "That was a great presentation!" is a nice compliment.

As a verb (the act of praising):

• The teacher complimented the students on their hard work.
• I have to compliment you on your excellent taste in music.

A Special Case: Complimentary

When something is complimentary, it's free.

• The hotel offers a complimentary breakfast.
• We got complimentary tickets to the show.

A Simple Memory Trick

Think of it this way: I love to get a compliment. The "i" in "compliment" is like the "I" in "I like it!"

Complement: The Perfect Match

A complement is something that completes or goes perfectly with something else.

How to Use "Complement"

As a verb (to complete or go well with):

• That wine complements the cheese perfectly.

Use COMPLEMENT when:
