侗台语复辅音pl、kl的演变分析

Analysis on the Evolution of the Consonant Clusters ~pl- and ~kl-in Proto0-Kam-Tai language

复辅音在现代侗台语中的分布不平衡,这是侗台语中部分古音发展演变的结果。复辅音 pl 和 kl 在侗台语中的比较分析表明,其演变途径分别为: pl 的演变方向比较一致,大都唇音化或舌音化成为单辅音; kl 则向舌根音或舌尖音演变,但不同语支之间演变进程不一。

The uneven distribution of consonant clusters in modern Kam\|Tai languages may be the specific results of historical development of some Proto\|Kam\|Tai initials.A probe into comparison of pl and kl in Kam\|Tai languages show that there are two different ways of their evolution:pl primarily changed into singular consonant through labialization and dentalization;while kl derived into velars and labials with divergent progresses in different subgroups.
