This document discusses the three types of speech acts: locutionary, illocutionary, and perlocutionary. Locutionary speech acts refer to the literal meaning of what is said. Illocutionary speech acts involve the intention behind what is said, such as making a promise or giving an order. Perlocutionary speech acts aim to change the feelings, thoughts, or actions of the listener through effects like inspiring, convincing, or scaring them. Examples of each type of speech act are provided.
