侗台语的■声母

The Initial■ in Tai-Kadai Languages

通过同源词比较,认为侗台语清鼻音声母■除了来自原始侗台语清鼻音*■的留存外,还可能来源于原始侗台语的清鼻音■*和*■。*■和*■在侗台语中发生了非线性音变。这两个来源可以解释侗台语部分语言的清鼻音■与一些亲属语言的khw、kw、kh相对应的现象。

This article analyzes and compares the cognate words in Tai-Kadai languages. It proposes that the voiceless nasal initial■ , besides being a remnant of the voiceless nasal■ , may also come from voiceless nasals *■ and *■ in Proto-Tai-Kadai. *■ and *■ have undergone nonlinear sound changes. These two sources serve to well explain the phenomenon that words with the initial ■have cognate words with initials khw, kw, or kh in languages such as Kam and Lakkia.
