Equatives are a construction indicating that two NPs are equivalent. For example in English, the sentence "Ray is the comedian" equates the two entities "Ray" and "Comedian". In Gaelic, equative constructions are often constructed using the Copula and a pronoun (typically e): 'S e Anndra an dotair" (although other constructions can be used for this purpose as well.
