How does pragmatics explain meanings that speakers imply without stating literally?

In the philosophy of language, pragmatics explains how speakers convey meaning beyond the literal definitions of their words. While semantics focuses on conventional word meanings, pragmatics analyzes how context and rational cooperation allow listeners to recover intended messages, known as implicatures.1

H.P. Grice famously theorized that conversation is governed by a Cooperative Principle, which assumes speakers intend to be informative, truthful, relevant, and clear. Listeners derive implied meanings when they assume the speaker is following these maxims, even if the literal utterance seems to violate them.2

Implicatures generally arise in three ways:
* Observance: When no maxim is violated, the listener infers meaning based on the assumption that the speaker is being relevant (e.g., mentioning a trip to New York to imply a connection to a person there).2
* Conflict: When a speaker violates one maxim to satisfy another, such as providing vague information to avoid making an unsupported claim.2
* Flouting: When a speaker blatantly ignores a maxim—such as using irony or withholding information in a recommendation letter—to signal that they intend to communicate something different from the literal statement.2
