白语方言中否定变韵的性质和来源

Nature and Origin of Rhyme-modification of Negative Verb Forms in Bai Dialects

白语方言中否定变韵的生成模式可以统ー为ー种,即V(肯定)→uV(否定),其中-u-来源于后置否定词~*mu^(33)。否定变韵的主要功能是情态意义的否定。根据否定变韵在方言中的分布,可以推断变韵是东支白语的创新变化,而不是原始白语的遗存。

This paper discusses the nature and origin of rhyme-modification of negative verb forms in Bai dialects. A generative rule of V （affirmative） → uV （negative） underlies various modification patterns. -u- comes from post-verbal negator ＊mu^33. Rhyme-modification is mainly applied to forms of modal negation, and is an innovation of the east branch of the Bai language, rather than retention of Proto-Bai.
