Firstly, we summed up the process and results of historical research. And then we classified the action morpheme and the noun morpheme. Based on the classification, we analyzed noun morphemes in order to find which kind of noun morpheme is strong to unite and which is the weak ones to centre around the action morpheme. Then we stated, analyzed and accounted for the usage of different semantic categories used in the line situation. We found that action morpheme combined into one by moving the line word was the main line and the main format, and explored and analyzed the role of analogy of noun morpheme line to other formats. Line formation of the word has its own reasons, so the article concluded by examining the formation of the line words' language, social and other reasons at last.
文章着眼于对动、名语素组合成的离合词的语义构成进行分析,探讨了动、名语素组合成离合词的语义选择规律,以动、名语素的语义分类为基点,在分类的基础上,以动语素为中心,分析围绕动语素的名语素义类,分析哪些义类名语素和动语素组合成离合词的能产性较强,即组合的周遍性和数量频度上是最高的,哪些义类组合成离合词的能产性比较弱,试图寻找动语素与名语素组合成离合词在义类上的能产性和周遍性,然后再对不同语义类组合中离合运用的情况进行统计、分析、说明。
