The Origin of Complement and Compliment

Both words come from the Latin word complere. It means “to fill up” or “to complete.”

Complement came into English from Latin through French. It kept the old idea of filling up. So it means “the thing that makes something whole.”

Compliment took a different road. It came through Italian and Spanish, where a similar word meant “polite manners.” Long ago, a compliment was a sign of good manners, like a kind greeting. Over time, it came to mean words of praise.

So they are cousins. They grew apart in meaning. Now only the spelling shows the family tie.
