 Grice's best-known example of conventional implicature involves the word 'but', which, he argues, differs in meaning from the word 'and' only in that we typically conventionally implicate something over and above what we say with the former but not with the latter.In uttering the sentence 'She was poor but she was honest', for example, we say merely that she was poor and she was honest, but we implicate that poverty contrasts with honesty (or that her poverty contrasts with her honesty).Grice makes it clear that what a speaker conventionally implicates by uttering a sentence is part of what the speaker means in uttering it, and that it is also closely connected to what the sentence means.
