西藏山南藏语方言的清鼻音和清边音

Voiceless Nasal and Lateral Sounds of Shannan Tibetan in Xizang

西藏山南部分藏语方言中存在书面藏语r N-声类词今读清鼻音、rl-声类词今读清边音的现象。本文结合藏语方言、文献材料以及音变的一般规律对清鼻音和清边音的来源以及演变进行探讨,认为该类清鼻音和清边音分别来源于早期的语音形式^(*)SN-和^(*)rl-,在演变上除浊化外,还存在向清喉擦音(N->h-、l->h-)发展的趋势。

In some varieties of Shannan Tibetan in the Xizang Autonomous Region,the Written Tibetan rN-initial is pronounced as a voiceless nasal and the rl-initial is pronounced as a voiceless lateral in some words.Based on data from Tibetan dialects and historical literature as well as the general rules of sound changes,I discuss the origin and development of the voiceless nasal and lateral sounds,proposing that these sounds develop respectively from early^(*)SN-and^(*)rl-sounds,and in addition to developing into voiced sounds,these sounds have the tendency of developing into the voiceless guttural fricative(such as N->h-and l->h-).
