discourse marker 的定义

In linguistics, a discourse marker is a word or phrase that is relatively syntax-independent and does not change the meaning of the sentence, and has a somewhat empty meaning. Examples of discourse markers include the particles "oh", "well", "now", "then", "you know", and "I mean", and the connectives "so", "because", "and", "but", and "or".
在语言学中,话语标记是指在句法上独立的一个单词或一个短语,它一般在句中起提示、停顿或过渡的作用,大多数时候没有实际意义,如果去掉也不会影响句子的意思.
英语中典型的例子有"oh", "well", "now", "then", "you know", and "I mean", and the connectives "so", "because", "and", "but", "or"等等.
