What are the four maxims under the cooperative principle？ And illustrate with one example how the violation of the maxim of quality gives rise to conversational implicature.
The four maxims under the cooperative principle are maxim of quality, maxim of quantity , maxim of relation, and maxim of manner.
When we violate any of these maxims, or language becomes indirect. and conversational implicature will arise, For example,
A: Would you like to come to our party tonight?
B: I’m afraid I'm not feeling so well today
This is said when it is known to both A and B that B is not having any health problem that will prevent him from going to a party, This B is saying something that he himself knows to be false and is flouting the maxim of quality. The implicature produced is "I do not want to your party tonight）
