Complement vs Compliment: Which One Do You Need?
Complement completes something. Compliment praises someone.
The wine complements the dish. She paid him a compliment.
The test that settles it
Look at the middle letter. Complement has an e, like complete — and that is what it does.
“The scarf ___ the coat” → it completes the outfit, so complements.
“He ___ her on the talk” → he praised her, so complimented.
Complement completes. Compliment is something I like to receive.
Complement: to complete or go well with
Both a verb and a noun. As a noun it can also mean the full number needed — a ship’s complement of crew.
The colours complement each other.
A full complement of staff was on duty.
These findings complement the earlier study.
Swap in completes or goes with. If it works, complement.
Compliment: praise
Both a verb and a noun. To compliment someone is to say something admiring; a compliment is that remark.
She complimented the chef.
Take it as a compliment.
He is fishing for compliments.
Swap in praise. If it works, compliment.

| Swaps with goes with | Swaps with praise |
| A complement of staff | A compliment on your work |
The exceptions
Complimentary usually means praising, but it also means free of charge — a complimentary breakfast.
Complementary, with the e, means fitting together: complementary colours, complementary skills.
In grammar a complement is the part of a sentence that completes the meaning of the verb, as in she is a doctor. It has nothing to do with praise.
