something that completes or pairs well
Something that makes another thing complete or better, or goes very well with it.
Patrón de uso:
[something] is a complement to [something]
Error frecuente:
Learners often confuse "complement" with "compliment". "Complement" (with an "e") is about completing or going well with something: "The sauce is a perfect complement to the meat." "Compliment" (with an "i") means praise: "He gave her a compliment on her cooking." Another mistake is using the wrong preposition; for this sense it is usually "a complement to" something, not "a complement of".

|
match (More general and informal; can mean simply that two things go well together, without the idea of completion.)
|
supplement (Focuses on adding something extra that is missing; less about natural harmony and more about filling a gap.)
Antónimos
clash (Used especially about colors, styles, or ideas that do not go well together.)
|
mismatch (Emphasizes that two things do not fit or work well together.)

to complete or go well with
To go well with something and make it better or more complete.
Patrón de uso:
[something] complements [something]
Error frecuente:
Learners often write *"compliment"* instead of "complement" for this meaning, especially after hearing it. Remember: "complement" is used when two things go well together ("The shoes complement the dress"), while "compliment" is used when you say something nice to someone ("He complimented her dress"). Another mistake is adding "with": in most cases we say "X complements Y", not *"complements with Y"*.
Sinónimos
enhance (Focuses more on improving quality, not always on completing or balancing another thing.)
|
balance (Stresses creating harmony or evenness; may not always imply completion.)
|
go with (More informal; often used about clothes, colors, or food that look or taste good together.)
Antónimos
clash (Used especially for colors, designs, or styles that look bad together.)
|
conflict (Emphasizes that two things do not work or fit well together.)

full number or amount needed
The full group or amount that is needed or usual in a situation.
Patrón de uso:
a full complement of [people/things]
Error frecuente:
Learners sometimes think this sense means "extra" people or things, but it actually means the full, correct number. Another error is using it without an article; in most cases you say "a full complement of" rather than just *"full complement of"* in standard written English.
Sinónimos
full staff (Informal and specific to employees; does not work well with non-human things.)
|
full quota (Often used when a fixed, allowed number is involved; slightly more technical.)
|
entire roster (Used more about lists of people such as teams; less general than "complement".)

set of all elements not in a set
In mathematics, all the items in the whole group that are not in a smaller group you are talking about.
Patrón de uso:
the complement of [set A] (in [set B])
Error frecuente:
Students sometimes confuse the complement of a set with its subset. A complement contains all elements not in the set (relative to some universal set), while a subset contains elements that are inside the set.
Sinónimos
set-theoretic complement (More explicit and technical term used in mathematics texts.)
Antónimos
subset (Not a strict logical opposite, but contrasts with focusing on elements inside the set instead of outside it.)

grammatical element completing meaning
In grammar, a word or group of words that you must add to a verb, noun, or adjective so that the sentence has a complete meaning.
Patrón de uso:
a [subject/object] complement
Error frecuente:
Learners often confuse complements with adjuncts. A complement is required to complete the meaning of the verb ("She put the book on the table" — "on the table" is a complement), but an adjunct is extra information that can be removed ("She read the book yesterday" — "yesterday" is an adjunct).
Sinónimos
predicative (Technical term often used for complements linked to the subject via a linking verb; more specific than "complement".)
Antónimos
adjunct (In grammar, an optional part of the sentence that is not required to complete the meaning of the verb.)
