汉语词汇历史发展过程中存在着这样一种有趣的现象:许多意义相反的两个单音词常常可以并列组合,以词组形式出现,中间不用连词连接。经过一段时间的使用,有一些成员不论从语义上还是从结构上都开始融合,凝固成一个复合词,“轻重”的词汇化便经历了这样一个过程。本文将在考察北大语料库大量语料的基础上系统梳理“轻重”的演变轨迹并归纳其词汇化的动因。 There is such an interesting phenomenon in the development of Chinese vocabulary history that many of the two monosyllabic words of opposite meanings can often be combined side by side and appear in the form of phrases with no conjunction in the middle. After a period of use, some members, both semantically and structurally, began to fuse into one compound word. The lexicalization of “light and heavy” went through such a process. Based on a large number of Corpus corpus of Peking University Corpus, this article systematically sorts out the evolution path of “light ” and summarizes its motivation of lexicalization.
