Quick Answer

Complement means something that completes or goes well with something else, while compliment means praise or a polite expression—one C completes, the other C congratulates.

Definition: Complement

Complement (noun/verb) refers to something that completes, enhances, or balances another thing. As a noun: "The wine is a perfect complement to the meal." As a verb: "The scarf complements her dress."

The word comes from the Latin complementum, meaning "that which fills up," which helps remember its sense of completion or fulfillment.

Definition: Compliment

Compliment (noun/verb) means praise, flattery, or a polite remark. As a noun: "He gave her a sincere compliment about her presentation." As a verb: "She complimented him on his kindness."

Compliment stems from the Italian complimento and Late Latin compliments, tied to expressions of courtesy—so think of it as speaking kindly to someone.
