Cooperative Principle Speech Act
12 Grice 1975: 45 divides implicature into two types; they are conventional
implicature and conversational implicature. Conventional implicature is associated with specific words and results in additional conveyed meaning when
those words are used. An example of the words is but in ‘He is poor but honest.’ The interpretation of this utterance will be he is poor and he is honest plus an
implicature of ‘contrast’ between the information. Contrast is the conventional implicature of but. Then, honesty is considered to be the opposite of having no
money. The second type of implicature is conversational implicature. It includes
context in understanding the additional conveyed meaning of an utterance. The meaning of an utterance in conversational implicature is indirectly stated in the
utterance. An example of utterances containing conversational implicature is In the following dialog:
Charlene : I hope you brought the bread and the cheese.
Dexter : Ah,
I brought the bread .
Yule 1996: 40 In the conversation, Dexter tries to convey an unstated meaning, that he
did not bring the cheese. As the listener, Charlene is expected to understand the unstated meaning of Dexter. Charlene should assume that Dexter is aware and
being cooperative. The unstated meaning inferred from the conversation above belongs to conversational implicature. Yule 1996: 42 puts this kind of
implicature into a more detailed type of implicature, which is a particularized conversational implicature.
13 Two other types of conversational implicature are a generalized
conversational implicature and a scalar implicature. The generalized conversational implicature is the opposite of the particularized conversational
implicature. The conversation of Charlene and Dexter above has a generalized conversational implicature. People do not need to have a special knowledge of
inferring the additional meaning. Scalar implicature happens when any forms of scale all, most, many, some,
few, always, often, sometimes are used in the utterance. The implicature can be gained by thinking of the negative of that scale. By saying ‘some students’, the
speaker implicates ‘not all students’. This is an example of scalar implicature, as a part of conversational implicature.
