 Grice justifies this neologism by saying that "'Implicature' is a blanket word to avoid having to make choices between words like 'imply', 'suggest', 'indicate', and 'mean'".Grice sums up these notions by suggesting that to implicate is to perform a "non-central" speech act, whereas to say is to perform a "central" speech act.As others have more commonly put the same distinction, saying is a kind of "direct" speech act whereas implicating is an "indirect" speech act.
