H. P. Grices Definition of Conversational Implicature
In the series of lectures at Harvard University in 1967, the English language philosopher Herbert Paul Grice (1913 - 1988) outlined an approach to what he termed conversational implicature how hearers manage to work out the complete message when speakers mean more than they say. The term refers to what is suggested in an utterance, even though not expressed nor strictly implied (that is, entailed) by the utterance [3, p. 189]. For example, the sentence Mary had a baby and got married strongly suggests that Mary had her baby before the wedding, but the sentence would still be strictly true if Mary had her baby after she got married. Further, if we add the qualification not necessarily in that order to the original sentence, then the implicature is cancelled even though the meaning of the original sentence is not altered.
H. P. Grice emphasized the distinction Voltaire makes in our opening quotation between what words mean, what the speaker literally says when using them, and what the speaker means or intends to communicate by using those words, which often goes considerably beyond what is said. In the utterance Have you got any cash on you? the speaker really wants the hearer to understand the meaning: Can you lend me some money? I dont have much on me. Or, say, I ask you to lunch and you reply: "I have a one o'clock class I'm not prepared for." You have conveyed to me that you will not be coming to lunch, although you haven't literally said so. You intend for me to figure out that by indicating a reason for not coming to lunch (the need to prepare your class) you intend to convey that you are not coming to lunch for that reason. The study of such conversational implicatures is the core of Grice's influential theory.
Grice's so-called theory of conversation starts with a sharp distinction between what someone says and what someone implicates by uttering a sentence. What someone says is determined by the conventional meaning of the sentence uttered and contextual processes of disambiguation and reference fixing; what he implicates is associated with the existence to some rational principles and maxims governing conversation. What is said has been widely identified with the literal content of the utterance; what is implicated, the implicature, with the non-literal, what it is (intentionally) communicated, but not said, by the speaker. Consider his initial example: A and B are talking about a mutual friend, C, who is now working in a bank. A asks B how C is getting on in his job, and B replies: Oh quite well, I think; he likes his colleagues, and he hasn't been to prison yet [8, p. 24].

What did B say by uttering "he hasn't been to prison yet"? Roughly, all he literally said of C was that he hasn't been to prison up to the time of utterance. This is what the conventional sentence meaning plus contextual processes of disambiguation, precisification of vague expressions and reference fixing provide.
But, normally, B would have implicated more than this: that C is the sort of person likely to yield to the temptation provided by his occupation.
The conversational implicature is a message that is not found in the plain sense of the sentence. The speaker implies it. The hearer is able to infer (work out, read between the lines) this message in the utterance by appealing to the rules governing successful conversational interaction.
According to Grice, the calculation of conversational implicatures is grounded on:
common knowledge of what the speaker has said (or better, the fact that he has said it),
the linguistic and extra linguistic context of the utterance,
general background information,
the consideration of what Grice dubs the cooperative principle (CP): 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 [8, p. 26].
