A connecting word, in particular a form of the verb be connecting a subject and complement.
- ‘In Hungarian, the zero copula occurs only in the third person, and in AAVE it is not permitted in the first person singular.’
- ‘The copula, is, serves to link the subject and predicate either as a form of classification or identification.’
- ‘In such cases they fulfil the basic requirement of Syriac sentence structure (namely, that the predicate must be conjugated for person) twice: once within the copula, and once within the verb of existence.’
- ‘The point of Hegel's critique is that there is more to the word ‘is’ than predication: the copula contains the implication that it identifies subject and predicate, rather than merely asserting that the predicate belongs to the subject.’
- ‘For linguists it is now standard to think of indefinite descriptions following the copula as always being predicational, and it is a widespread belief that definite descriptions following the copula are often predicational.’
Early 17th century: from Latin, connection, linking of words from co- together + apere fasten.
