According to relevance theory, irony comprehension invariably entails the identification of some opinion or thought (echo) and the identification of the speaker’s dissociative attitude. In this paper, it is argued that it is also essential for hearers to identify not only that propositional attitude, but also the affective attitude that the speaker holds towards the source of this echo so that an optimally relevant interpretive outcome is achieved. This notion comprises feelings and emotions of a non-propositional quality which affect the propositional effects obtained in ironical communication. The paper further argues for the need to incorporate non-propositional effects into the traditional propositional object of pragmatic research.
