 As we observed in  §1,  Grice defined implicating as a form of speaker meaning. But Grice and others nevertheless began applying “implicate” to sentences, analogous to the way “imply”, “presuppose”, and “mean” apply to sentences as well as people.  [18]  If an implicature is conventional in either sense (that is, either semantic or generalized), we may say that the sentence implicates it, or has the  implicature.[19]  Even though Barb implicates that she is not going to Paul’s party, “I have to work” does not itself implicate this. But “Some athletes smoke” implicates that not all do even though speakers can use the sentence without implicating this. (Analogy: plane means “airplane” even though speakers can use plane without meaning “airplane”.) Similarly,  (4b)  implies that Trump is a stable genius even though speakers can use it without implying that.
