【正确答案】正确答案：According to Austin, a speaker might be performing three acts simultaneously when speaking. A locutionary act is the uttering of words, phrases, and clauses, which conveys meaning by giving out meaningful sounds. Therefore, when somebody says "Morning", we can ask a question like "What did he do?" , and the answer could be "He offered a greeting. An illocutionary act is the act of expressing the speaker's intention; it is the act performed in saying something. Therefore, for the same example, we can say "He meant it as a greeting". A perlocutionary act is the effect of the utterance. Thus, by saying "Morning!" the speaker has made it clear that he wants to keep friendly relations with the hearer.
