What does copular mean?
Copular is an adjective used chiefly in linguistics and grammar to describe something relating to, or functioning as, a copula — the type of verb that links a grammatical subject to information about it rather than expressing a physical action. In a sentence like "The sky is blue," the verb "is" does not describe an event but simply connects the subject to its description; this linking behaviour is what makes it copular. Verbs such as "be," "seem," "become," and "appear" are commonly classified this way, and linguists speak of copular verbs, copular sentences, and copular constructions when analysing them. The term derives from the Latin word for a bond or tie, reflecting its connecting role, and it also has a long-standing use in logic, where a copula links a subject term to a predicate. Though technical in register, it is a precise and useful word for anyone studying how sentences are built.

"In the sentence "The soup is cold," the verb "is" serves a copular function, linking the subject to its complement."
"In "The verdict was unanimous," the verb "was" performs a copular role, joining the subject to its complement."
"Linguists classify verbs like "seem" and "become" as copular because they connect rather than convey action."
Every time you say "she seems tired" instead of "tires she," you are using one of English's quietest verbs doing what linguists call copular work.

Etymology of copular
The word copular comes from Latin, ultimately from the noun "copula," meaning a bond, link, or tie, which itself derives from the Latin verb "copulare," meaning to join or couple together. It entered scholarly English usage alongside "copula" in the context of formal logic, where the copula was the element connecting subject and predicate, and later became established in linguistic terminology for linking verbs. It shares this Latin root with words such as "couple" and "copulate," all built on the same idea of joining things together.
How copular is actually used
Primarily a technical term used in linguistics, grammar teaching, and logic; rarely encountered in everyday conversation. It appears almost exclusively attributively before nouns such as "verb," "sentence," or "construction." The related noun "copula" is more widely known than the adjective form.
Easily confused with copular
Corpuscular means consisting of tiny particles (corpuscles), as in corpuscular theory of light, whereas copular relates only to linking verbs in grammar.
A copula is the linking verb itself (the noun), while copular is the adjective describing anything relating to or characteristic of such a verb.
