In linguistics, sentence function refers to a speaker's purpose in uttering a specific sentence, phrase, or clause.
在语言学中,功能句是指说话者所讲的具体,短语或从句的目的.
Whether a listener is present or not is sometimes irrelevant. It answers the question: "Why has this been said?" The four basic sentence functions in the world's languages include the declarative, interrogative, exclamative, and the imperative. These correspond to a statement, question, exclamation, and command respectively. Typically, a sentence goes from one function to the next through a combination of changes in word order, intonation, the addition of certain auxiliaries or particles, or other times by providing a special verbal form. The four main categories can be further specified as being either communicative or informative
