The etymology of compliment & complement
Complement and compliment share an origin and come from the same Latin word, complere, “fill up”. Complement is still true to its original Latin meaning, “to fill up, finish, suit”. ‘Compliment‘, on the other hand, has strayed from its etymological definition and now refers to “pay a compliment to, flatter or gratify by expression of admiration, respect, etc.”
To remember the difference, think of “complement” as short for “complete“, meaning something that completes or perfects something else.
**compliment** (praise) has an ‘I’ like ‘I love it!’ **Complement** (complete) has an ‘E’ like ‘Enhance.’.
