The document discusses Paul Grice's theory of conversational implicature and how speakers imply meanings beyond what they literally say through observations of the cooperative principle and its maxims of quality, quantity, relation and manner. It provides examples of how implicatures can be inferred from utterances that seem to violate these maxims. The cooperative principle aims to explain how listeners can understand a speaker's intended meaning, even when the utterance appears untrue, unrelated or absurd on the surface.
