云龙白语a3？、ni？21词缀研究
Research on the “a3？” and “ni？21” Affixes in Yunlong Bai Language

“ni？21”和“a3？”词缀是云龙白族亲属称谓中常用的两个词缀。“阿”类词缀在藏缅语族诸语言的亲属称谓中使用较为普遍，属于汉藏语系中比较古老的同源底层。“ni？21”词缀是从“ni？3？”的音节脱落而来，“ni？21”的意义正处于一个不断虚化的过程之中，未来有可能完全虚化成词缀。
The “ni？21” and “a3？” suffixes are two commonly used affixes in the kinship terms of the Bai people in Yunlong. The “Ah” class affixes are widely used in the kinship terms of various languages in the Tibeto-Burman language family and belong to the older proto-root layer in the Sino-Tibetan language family. The “ni？21” suffix originated from the syllable shedding of “ni？3？”, and the meaning of “ni？21” is in a continuous process of grammaticalization, which may eventually become a completely grammaticalized affix.
