This document discusses the cooperative principle in pragmatics. It explains that cooperation is essential for successful conversation, as the speaker and listener must work together towards the same end. It describes Paul Grice's cooperative principle from 1975, which states that conversation participants intend to communicate something through their words. Grice outlined four maxims of conversation - quality, quantity, relation, and manner - which provide guidelines for effective language use. The maxims require truthful, informative, relevant contributions delivered clearly and briefly. Understanding and following these pragmatic principles leads to successful conversational cooperation.
