What does copulative mean?
Copulative is primarily a grammatical term describing words that link rather than act. A copulative verb — also called a linking verb — connects a subject to a complement that renames or describes it, as when 'becomes' works in 'the night becomes cold'; 'be', 'seem', 'appear', and 'become' are the classic examples. In logic, a copulative proposition joins two assertions with 'and'. More generally, the adjective can describe anything that serves to join or bind together, and in older or technical prose it may refer to sexual union, though this sense is now largely confined to medical and zoological contexts. The word descends from Latin copulare, 'to join', itself built on copula, 'a bond or tie' — the same root behind 'couple'. As a noun, a copulative is simply one of these linking verbs. It is a formal, specialist word: useful for precise discussion of grammar and logic, but likely to raise eyebrows if used loosely.
(Grammar) Serving to connect a subject with a complement rather than to express an action; also, more generally, serving to join or link things together.
"Traditional grammars classify 'seem' as a copulative verb."
In modern linguistics, 'copular' is the more common adjective for linking verbs.
A copulative verb; a word such as 'be' or 'become' that links a subject to a predicative complement.
"In 'the verdict seems fair', 'seems' acts as the copulative."
Used only for the noun sense referring to linking verbs.
"Grammarians have long debated how best to treat copulatives such as 'appear' and 'remain'."
The same Latin word that gives us 'couple' also names the humble verb 'to be' — grammar's quiet connector and, elsewhere, a very unquiet act.

Etymology of copulative
Copulative comes from late Latin copulativus, derived from copulare, 'to join or couple together', which in turn rests on the noun copula, meaning 'a bond, tie, or link'. English adopted the word in the mid-16th century, first in general use for things that join, before it settled into grammatical terminology for verbs that link subject and predicate. The same Latin root produced 'copulate' and 'copulation' (sexual union) and, via Old French, the everyday word 'couple', making them all close cognates.

How copulative is actually used
The grammatical sense dominates in modern usage and appears mainly in linguistics, logic, and traditional grammar teaching. The sense relating to sexual union is technical and rare outside medical or zoological writing, where 'copulatory' is usually preferred; the overlap can make 'copulative' sound faintly risible out of context.
Easily confused with copulative
'Copular' is the narrower linguistic term for verbs like 'be' that link subject and complement, while 'copulative' is broader and can also mean joining in general or relating to sexual union.
'Copulatory' refers specifically to sexual coupling, whereas 'copulative' more often describes grammatical or logical linkage.
