试论古汉语中的“鸳鸯”是否是联绵词——兼论联绵词的一种鉴别方式

在现代汉语中“鸳鸯”是联绵词。通过对“鸳鸯”的历时考察，发现“鸳”、“鸯”能单用、分用，有重叠形式，“鸳鸯”有异序词，也和合成词一样。所以用现行的有关联绵词的语素识别方法一双向替换法不好判断它是否是联绵词。通过考察联绵词的来源，提出了新的判断方法，用两个公式区分联绵词与合成词，最终确定“鸳鸯”从古至今都是联绵词。

Is the Word ＂Yuan Yang＂ a Binome？ ——on Ways of Identifying Binome

The word ＂Yuan Yang＂ is considered as a binome in modem Chinese. In this paper, through diachronic investigation on the word ＂Yuan Yang＂ , we find that ＂Yuan＂ , ＂Yang＂ can be used alone or separately;they have overlapping forms. Meanwhile,like the compound word, ＂Yuan Yang＂ also has allotropy. From these phenomenons we can see that it is difficult to see whether the word ＂Yuan Yang＂ is a binome or not when we use the existing methods of bidirectional substitution. By exploring the source of binomes, we raise new judgment methods, namely, two formulas to distinguish binomes and compound words. We finally maintain that the word ＂Yuan Yang＂ is a binome since ancient times.
