Quick answer
A compliment is a nice remark you give someone; a complement is something that completes or pairs well with something else. A kind word is a compliment; a matching accessory is a complement.
These two words are pronounced identically and differ by only one letter, which makes them a classic source of typos even among careful writers. Their meanings, though, don’t overlap at all.
Quick Answer
Compliment (with an i) is praise — a nice thing you say about someone. Complement (with an e) means something that completes, enhances, or pairs well with something else. “She paid me a compliment” versus “the scarf complements the dress.”
Definitions
Compliment can be a noun or verb related to praise or admiration. As a noun: “that was a generous compliment.” As a verb: “he complimented her presentation.”
Complement can also be a noun or verb, but it’s about completeness or a good match. As a noun: “the wine is a perfect complement to the meal.” As a verb: “the sauce complements the fish.” In grammar, a “complement” is also a specific technical term for a word or phrase that completes the meaning of a verb or subject.
The Key Difference
Think of the “i” in compliment as standing for “I like it” — it’s about praise. Think of the “e” in complement as standing for “extra” or “enhance” — it’s about making something more complete. If you’re praising a person, use the i-spelling. If you’re describing how two things go together, use the e-spelling.
Praise (compliment)
Thank you for the compliment on my presentation.
Pairing (complement)
The bookshelf complements the rest of the room’s furniture.
Verb, praise
She complimented the chef on the dessert.
Verb, pairing
These two colors complement each other beautifully.
| Compliment | Complement | |
|---|---|---|
| Meaning | Praise or admiring remark | Something that completes or enhances |
| Part of speech | Noun or verb | Noun or verb (also a grammar term) |
| Memory letter | I — “I like it” | E — “enhance” or “extra” |
| Example | a sincere compliment | a perfect complement |
Common Mistakes
- Writing “the shoes complement her” when you actually mean “compliment” — pairing versus praise.
- Writing “that’s quite a complement” instead of “compliment” when talking about a kind remark.
- Mixing up the verb forms: “complimenting the outfit” (praise) versus “complementing the outfit” (matching it).
- Forgetting the grammar-specific sense of complement, which trips up writers revisiting sentence structure rules.
Memory Trick
“I” compliment you — the word for praise has an I, just like the word “I.” Complement, with an E, completes a pair, and both “complement” and “complete” share that same E-M-P-L pattern.
