Implicature (Stanford Encyclopedia of Philosophy)
Since it involves meaning one thing by saying something else, it is an indirect speech act, albeit not one that Searle (1975: 265–6) analyzed. By “saying”, Grice meant not the mere utterance of words, but saying that something is the case, another illocutionary speech act. Barb could have said the same thing by uttering different words.
