汪锋、龚希劼 白语方言中否定变韵的性质和来源

北京：《民族语文》2016 年第 5 期. — 39-46页.白语方言中否定变韵的生成模式可以统一为一种，即 V（肯定）→ uV（否定），其中-u-来源于后置否定词*mu33。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 *mu33. 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.
