从产生机制上分析“死于了非命”句的合格度,兼论语言规范与语言使用的关系。认为“死于了非命”句的使用有其句法和心理依据,即类推造句和优选,属于语言在使用中的变异。作为影视台词和日常口语有其合法性和可解性,但该句不具有能产性,因此不是语言创新。 From the mechanism of production, we analyze the degree of eligibility of sentences that die of non-life and the relationship between language norms and language usage. It is believed that the use of the phrase “died of non-life” has its syntactic and psychological basis, that is, the analogy of making sentences and preferences is a variation in the use of language. As the film’s lines and daily spoken language has its legitimacy and solvability, but the sentence does not have productivity, it is not a language innovation.
