【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 act of saying, the literal meaning of the utterance. 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 extra meaning of the utterance produced on the basis of the literal meaning. Therefore, for the same example, we can say " He meant it as a greeting". A perlocutionary act is the effect of the utterance on the hearer. Thus, by saying " Morning!" the speaker has made it clear that he wants to keep friendly relations with the hearer.
