A clear overview, the key differences, word origins, and plenty of examples.
“Complement” and “compliment” are homophones: they sound exactly alike but mean very different things, and they’re among the most commonly confused words in English. The difference hangs on a single letter. A compliment (with an i) is praise. A complement (with an e) is something that completes. This overview breaks down the meanings, the key differences, where each word came from, and how to use them, with examples throughout.
Quick Answer:
Use compliment (i) for praise or a kind remark: “What a lovely compliment.” Use complement (e) for something that completes or enhances another thing: “The sauce complements the dish.”
Overview: Compliment vs. Complement
Both words trace back to the same Latin root but split into two distinct meanings over time. Here’s the big picture before we dig into details.
| Word | Core Idea | One-Line Meaning |
|---|---|---|
| Compliment (i) | Praise | A kind remark, or to give one |
| Complement (e) | Complete | Something that completes or enhances, or to complete |
What Does Compliment Mean?
Compliment (with an i) is about praise. It can be a noun (a kind remark) or a verb (to give praise).
Compliment as a Noun
✓ She gave me a lovely compliment on my presentation.
✓ Please accept this as a sincere compliment.
Compliment as a Verb
✓ He complimented her on the new design.
✓ The chef was complimented for the meal.
Memory Trick: The i in compliment stands for “I like it” or “I’m praising you.”
What Does Complement Mean?
Complement (with an e) is about completing. It can be a noun (something that completes) or a verb (to complete or enhance).
Complement as a Noun

✓ The hat was a stylish complement to her outfit.

Bonus: Complement in Grammar
In grammar, a complement is a word or phrase that completes the meaning of a verb or subject. For example, in “She is a doctor,” the phrase “a doctor” is a subject complement. This is an extra meaning worth knowing, but it still uses the e spelling.
Key Differences at a Glance
| Aspect | Compliment (i) | Complement (e) |
|---|---|---|
| Core meaning | Praise or admiration | Something that completes |
| Parts of speech | Noun and verb | Noun and verb |

Where Do These Words Come From?
Both words come from the Latin complementum, meaning “something that completes.” Complement kept that original “completing” sense. Compliment branched off through Italian and French, where it came to mean an expression of politeness or praise. So the two words are distant cousins, not spelling variants, which is exactly why their meanings are so different today.
Complimentary vs. Complementary
The same i/e split carries into the adjective forms, which cause just as much confusion.
| Word | Meaning | Example |
|---|---|---|
| Complimentary (i) | Praising, or free of charge | A complimentary room upgrade. |
| Complementary (e) | Combining well to complete each other | Complementary skills on a team. |
Quick Tip: A free gift or kind words are “complimentary” (i). Two things that work well together are “complementary” (e).
Common Mistakes to Avoid
| Meaning Intended | Incorrect | Correct |
|---|---|---|
| Praise | Thanks for the compliment! | |
| Good pairing | The wine complements the meal. | |
| Free item | a complimentary breakfast | |
