Conversational implicature
Conversational implicatures are, roughly, things that a hearer can work out from
the way something was said rather than what was said.
People process conversational implicatures all of the time and are mostly unaware of
it. For example, if someone asks “Could you close the door?” the hearer does not
usually answer “Yes”, instead they perform the non-linguistic act of closing the
door. In this case, although the speaker used a form of words that is conventionally a
question, the hearer can infer that the speaker is making a request.
Grice was the first to note this ubiquitous feature of language use and also the first to
present a philosophical analysis. He begins by noting that conversations are usually
to some degree cooperative enterprises.
He then formulates the Cooperative Principle: “Make your conversational
contribution such as is required, at the stage at which it occurs, by the accepted
purpose or direction of the talk exchange in which you are engaged” (1989, 26).
At a more detailed level, he distinguishes four categories with more specific
maxims.
The category of Quantity includes two injunctions, one to make your contribution
as informative as is required, and the second to make it no more informative than is
required.
The category of Quality is governed by a supermaxim: “Try to make your
contribution one that is true”. tell the truth
The category of Relation has a single maxim, “Be relevant”.
The category of Manner has a short “super” maxim “Be perspicuous”.
