This document discusses speech acts and their different types. It defines a speech act as something expressed that both conveys information and performs an action. Speech acts have three components: locutionary, illocutionary, and perlocutionary. The locutionary act is the literal meaning of an utterance, while the illocutionary act is the intended purpose, such as requesting or asserting. There are five types of illocutionary acts: directives, expressives, commissives, assertives, and declaratives. The perlocutionary act is the actual effect on the listener, intended or not, like persuading or inspiring them.
