豫鄂陕交界区域汉语方言合口介音的消失

The Medial-u Loss in Chinese Dialects of the Border Area of Henan(河南)-Hubei(湖北)-Shanxi(陕西) Provinces

中古非唇音合口字-u-介音消失是豫鄂陕交界区域汉语方言的区域特征。总体来看,该区域方言合口介音呈现出明显的循序渐进性,从声组看,合口介音消失顺序为端泥>精>知>见;从韵摄看,合口介音消失顺序为蟹止>山臻>通。合口介音消失的次序与声母、韵母的发音机制有关。

This paper roundly investigates the types and geographical distribution of the medial-u loss in Chinese dialects of the border area of Henan（河南）-Hubei（湖北）-Shanxi（陕西） provinces. The loss of non-labial medial-u in Middle Chinese is the characteristic of this region. To summarize, the medial-u loss in dialects of this area show obvious gradualness. In the light of the ancient initials, the order of the loss of medial-u is ＂duan ni（端泥）＂〉＂Jing（精）＂ 〉＂zhi（知）＂〉＂jian（见）＂; According to the ancient vowels, the order of the Loss of medial-u is ＂xiezhi（蟹止） ＂〉＂shanzhen（山臻）＂〉＂tong（通）＂. This study considers there is a relationship between the order of the medial-u loss and oronunciation mechanism of initials and vowels.
