According to Austin's model， a speaker might be performing three acts simultaneously when speaking: locutionary act, illocutionary act, and per locutionary act Illocutionary act is the act of expressing the speaker intention (conveying meaning in context; the intention of the speaker while speaking). It is the act performed in saying something. For example， in the sentence “I am thirsty”， the propositional meaning is what the utterance says about the speaker's physical state. The illocutionary force is the effect the speaker wants the utterance to have on the listener. It may be intended as request for something to drink.
