从泰汉关系词看中古汉语三四等韵差异

The Distinction Between the Third Rhyme and the Fourth Rhyme in Mediaeval Chinese from the Perspective of the Words of the Same Etymology in Chinese and the Language of Thailand

泰语中存在大量的汉语借词或跟汉语历史关联的同源词,这些关系词不仅可用来构拟上古汉语和原始共同语,而且可以用来考查中古时期的语音状况。从汉泰关系词的三等韵、四等韵的不同表现,可以看出三等韵跟四等韵在汉语里曾经存在的差异,即在三等韵字产生介音的时候,四等韵还没有介音。

In the language of Thailand,words borrowed from Chinese or words of the same etymology with Chinese words are in great abundance.These words are of value not only in the construction of the proto-language and of ancient Chinese,but also in investigating the phonetic condition of Mediaeval times.In the present paper,the distinction of the third rhyme is dealt with from the perspective of the difference between the words of the third rhyme and of the fourth rhyme in Chinese and in the language of Thailand.
