actant. The basic unit in the structural-semantic analysis of narrative proposed by GRElMAS, who draws on PROPP'S morphological analysis of folk-tales. An actant is not defined in psychological terms as a 'character', but as a functional unit with a predicate defined by what it does. Greimas identifies six such actants and orders them into the following binary oppositions: Subject/Object, Sender/Receiver, Helper/Opponent. Although Greimas's original analysis of the actant function refers to quest-narratives, the actant is assumed to be a universal feature of all narratives.
