Pragmatics

Pragmatics is the branch of linguistics and philosophy of language concerned with how context determines what utterances mean beyond — and sometimes against — their literal semantic content. Where semantics asks what a sentence means in virtue of its structure and the meanings of its parts, pragmatics asks what a speaker communicates by uttering that sentence in a particular context to a particular audience.

The founding observation: the same sentence can communicate different things in different contexts. 'Can you pass the salt?' is grammatically a question about capability, but pragmatically a request. 'It's cold in here' said by a guest to a host communicates a desire to close the window. 'That's a great idea' said with a certain intonation can communicate its opposite. Pragmatic competence — knowing how to interpret these utterances correctly — is as central to language use as semantic competence, and arguably more fine-grained.

Paul Grice's theory of conversational implicature is the foundational formal account of pragmatics. Grice proposed that speakers and hearers cooperate according to a Cooperative Principle: be as informative as required, truthful, relevant, and perspicuous. When a speaker violates one of these maxims obviously and deliberately — e.g., says something clearly false for comic effect — the hearer infers that the speaker is communicating something other than what the words literally say. The inference is the implicature.

Grice's framework was extended and partially replaced by Relevance Theory (Sperber and Wilson), which reduces all pragmatic inference to a single principle: hearers always interpret utterances by seeking the reading that maximizes relevance — informational gain relative to processing cost. This is both a psychological and a communicative claim: language is a tool for manipulating others' representations, and its pragmatic dimension is the dimension of that manipulation.

Speech Act Theory — developed by J.L. Austin and John Searle — adds a further layer: utterances do not merely convey information but perform actions. Promising, ordering, apologizing, and declaring are illocutionary acts that change the social world by being successfully performed. Pragmatics, on this view, is not merely interpretation — it is participation in the social construction of shared reality.
