 The notion of an illocutionary act was introduced by Austin by means of examples (1962 [1975: 98–102]), and that is the normal procedure. Illocutionary acts are such acts as asserting, asking a question, warning, threatening, announcing a verdict or intention, making an appointment, giving an order, expressing a wish, making a request. An utterance of a sentence, i.e., a locutionary act, by means of which a question is asked is thus an utterance with interrogative force, an if an assertion is made, it has assertoric force.
