Which one to use?Intermediatenoun / verbnoun / verb

ComplementvsCompliment

One means to complete or enhance something; the other is praise or a flattering remark.

Side-by-side comparison

Complement
noun / verb

Noun/verb. Something that completes or enhances another thing. The two parts fit perfectly together.

  • The wine was a perfect complement to the meal.

  • The blue scarf complements your eyes beautifully.

  • Their skills complement each other well.

Compliment
noun / verb

Noun/verb. A polite expression of praise or admiration directed at someone.

  • He paid her a genuine compliment on her presentation.

  • She complimented the chef on the extraordinary flavor.

  • Accept the compliment gracefully and say thank you.

Common mistake

  • •"The colors really compliment each other" is wrong: when two things go well together, the verb is "complement" (with E).
  • •"Compliment" with I is the praise or kind remark.

Trick to remember it

  • •"Complement" with E comes from "complete", it fills a gap.
  • •"Compliment" with I is what you say when something Impresses you.

Quick rule

  • •"Complement" (with E) = to complete or go well with.
  • •"Compliment" (with I) = to praise or say something kind.

Did you know?

Both words come from Latin "complementum" (what completes), but they took different paths through medieval French before reaching English. "Compliment" passed through Italian "complimento" (courtesy gesture) before entering English in the 17th century. "With compliments" is the formal phrase printed on corporate gift cards. And "complimentary" (with I) has two meanings: "free of charge" and "flattering", so "complimentary breakfast" = free breakfast, and "complimentary review" = flattering review.
