Perlocutionary act

A perlocutionary act is a concept from speech act theory, primarily developed by philosophers like J.L. Austin and John Searle. It refers to the effect or outcome that a speaker's utterance has on a listener. While locutionary acts pertain to the actual words spoken, and illocutionary acts concern the intention behind those words, perlocutionary acts focus on the response or reaction they evoke in the audience.
