How can the sentence “I am cold” function as a request to close a window?

In the study of language, the sentence “I am cold” is a classic example of an indirect speech act. While semantics focuses on the literal or conventional meaning of words and sentences, pragmatics examines how utterances are used to communicate intentions beyond those literal meanings based on the context in which they occur.12

According to speech act theory, developed by J.L. Austin, an utterance can function on three levels:
* Locutionary act: The literal act of saying the words “I am cold”.2
* Illocutionary act: The intended action performed by the speaker, such as requesting or demanding that the listener close a window.23
* Perlocutionary act: The actual effect produced, such as the listener closing the window.2

When a speaker says “I am cold,” they are performing an indirect speech act by using a statement to achieve a directive goal. The listener understands this request by considering the physical context and the principle of rational cooperation in conversation.12
