Since the proposal by Austin (1962) and Searle (1969), Speech Act Theory has become established as an important theoretical framework in linguistics and pragmatics. In this theory, speech acts are classified into three types: locutionary acts, illocutionary acts, and perlocutionary acts. Specific linguistic acts such as requests, apologies, invitations, and expressions of gratitude are theoretically explained in various texts and dictionaries as belonging to illocutionary acts.
