现代汉语中存在“N人”一类说法。“N人”表达集合义,可以从其前后成分中得到验证;“N人”显示个体义,主要从其前数量词语或后现表人名词中得到体现。根据“N人”句法语义上的差别,我们将“N人”分为A、B、C三类,认为三类存在一个稳定性和可接受性渐弱的序列。最后从“N人”的经济性、“N人”与“N的人”组合的对比以及“N人”的命名作用等方面探讨“N人”的语用价值。 There is a class of “N people” in modern Chinese. The “N-person” expression sets the meaning of justice, which can be verified from its components. The “N-person” shows the individual righteousness, which is mainly reflected in its former quantitative terms or the post-appearance nouns. According to the syntactic and semantic differences of “N people”, we classify the “N people” into A, B and C categories, and consider that there is a series of three types of stability and acceptability receding. Finally, the paper discusses the pragmatic value of “N” from the aspects of economy of “N”, comparison of “N” and “N” and Naming of “N”.
