In linguistics and the philosophy of mind, a locutionary act is the performance of an utterance, and hence of a speech act. The term equally refers to the surface meaning of an utterance because, according to J. L. Austin's posthumous "How To Do Things With Words", a speech act should be analysed as a locutionary act (i.e. the actual utterance and its ostensible meaning, comprising phonetic, phatic and rhetic acts corresponding to the verbal, syntactic and semantic aspects of any meaningful utterance), as well as an illocutionary act (the semantic 'illocutionary force' of the utterance, thus its real, intended meaning), and in certain cases a further perlocutionary act (i.e. its actual effect, whether intended or not).
