In the daily conversation, it is often found some people who order or command someone do not use the imperative sentence which has function to order someone. More people are using question, even statement sentences to order someone which grammatically has function to ask and give information to listener. However, the response that performed by the listener is like getting command with imperative sentence. That is one of the reasons why a person needs to learn Pragmatics. In the pragmatic, Cahyono (1995) assumes that the meaning of utterance is assessed according to the meaning intended by speakers and by the context. Webster (2004) defines that order is to give authoritative instruction to someone to do something or for something to be done. On his book, Pardiyono (2005) explains that each sentence has different function, and it is depend on its type. For example, the question that is used to ask information is declarative or question sentence, and the sentence that is used to order someone is called as imperative or command sentence.
