Use complement to mean something that completes or goes well with (the wine complements the meal). Use compliment to mean praise (she paid me a compliment).
The Core Difference
“Complement” (with an E) means something that completes, enhances, or perfectly matches something else, making a whole: the scarf complements her outfit, a full complement of staff.
“Compliment” (with an I) means an expression of praise or admiration, either as a noun or a verb: he paid her a compliment, she complimented his cooking.
- completes / matches → complement: the colours complement each other
- praise / admiration → compliment: thank you for the compliment

Common Mistakes
| Incorrect | Correct | Why |
|---|---|---|
| ✗ thank you for the complement | ✓ thank you for the compliment | praise |
| ✗ the shoes compliment the dress | ✓ the shoes complement the dress | matching / completing |
| ✗ he payed me a nice complement | ✓ he paid me a nice compliment | praise |
| ✗ a full compliment of staff | ✓ a full complement of staff | complete set |
| ✗ she complemented his singing | ✓ she complimented his singing | praise |
Compliment has an I, like “I like it!” — praise is about liking something. Complement has an E, like “complete” — both words share the letters C-O-M-P-L-E, and both are about completeness.

Frequently Asked Questions
What is the fastest way to tell complement from compliment?
Remember: “complEment” shares its spelling with “complEte” (both have an E) and relates to completing or matching. “complIment” contains an I, and praise is about saying “I like it” — a personal reaction.
Can compliment be used as a verb?
Yes — “to compliment” means to praise someone: “She complimented him on his speech.” It is used just as commonly as the noun form “a compliment”.
Is complement only used with things, not people?
No — “complement” can describe people too, especially teamwork: “Their skills complement each other” means their different strengths combine to form a more effective whole.
What does full complement mean?
“Full complement” means the complete number required for something to function properly, often used for staff, crew, or equipment: “The ship sailed with a full complement of 200 sailors.”
Is complementary the same as complimentary?
No, they are different words with different meanings despite looking similar. “Complementary” (with an E) means completing or matching, as in “complementary colours”. “Complimentary” (with an I) means either given as praise, or given free of charge (a complimentary drink).
Why does complimentary mean free?
“Complimentary” came to mean “free” because giving something without charge was originally seen as a gesture of goodwill or a compliment to the recipient — “a complimentary breakfast” is one offered as a courtesy.
How do I remember complementary colours?
“Complementary colours” (like red and green) are colours that, when combined, complete or balance each other visually — link it to “complete” and the E spelling, the same way as “complement”.
Is backhanded compliment a real expression?
Yes — a “backhanded compliment” is a remark that seems like praise but contains a hidden insult, for example, “that dress is surprisingly flattering on you.” It always uses “compliment” (praise), never “complement”.
Do grammar checkers catch this mistake?
Basic spell-checkers usually do not, since both “complement” and “compliment” are correctly spelled real words — only context-aware grammar tools or careful proofreading will catch a wrongly chosen word.
Is this distinction tested in professional writing?
Yes — because the words are used frequently in business contexts (product descriptions, customer service, HR feedback), mixing them up is a common and noticeable error in professional and academic writing.
