This document discusses speech acts, which refer to communicative utterances within a context. There are three aspects of a speech act: the locution is the physical utterance, the illocution is the intended meaning, and the perlocution is the resulting action. Speech acts can be categorized into constatives like affirming, directives like ordering, and commissives like promising. The theory of speech acts analyzes the locutionary act of saying something, the illocutionary act of performing an intended function in saying it, and the potential perlocutionary effect on the listener.
