【Abstract】 The discourse marker ke yi shuo develops from the lexicalization of the speech phrases ke yi shuo. Ke yi shuo generally appears with other units, which is usually distributed at the beginning, middle or the end of a turn, corresponding to three structural modes of ke yi shuo + follow-up sentence, former sentence + ke yi shuo + follow-up sentence and former sentence + ke yi shuo, which has the functions of introducing the topic, connecting the preceding and the following sentences, and strengthening the affirmation. The pragmatic meaning of the discourse marker ke yi shuo is evolved from the meaning of can be said or allow to be said of the phrase ke yi shuo. Ke yi shuo has a function of topic regulation, sequence filling, emotion expression and interaction enhancement, and its formation mechanism is based on lexicalization and absorption of context.更多还原
