蒋藏本《唐韵》异常音切考察

The survey of some different Fanqie from Tang Yun of Jiang's version

蒋藏本《唐韵》存在一些与其他韵书不同的切语,这些切语反映的实际语音现象有:1.浊声母开始或正在清化过程中;2.唇音开始或已经从重唇音中分化出来,轻唇音的非敷两母开始或已经合并;3.二等重韵的卦、怪、夬有合并的迹象。

As for Tang Yun(唐韵),one ancient rhyme dictionary with its missing pages recollected byJiang Fu(蒋斧)(usually entitled JCB in related linguistic literature),there are some differentFanqies from other relevant works in terms of initials,rhymes and single characters.By utilizingthese differences,the phonological reality can be postulated and reconstructed during that period oftime:(1)the complete voiced initials are in the course of devoicing;(2)the character lie(劣)begins to be pronounced in a open-mouth way;(3)labio-dentals have already distinguishedthemselves from the bilabials,and the initials fei(非)and fu(敷)begin or have begun toconverge;(4)The second-division rhymes such as gua(卦),guai(怪),and guai(夬)haveshown the tendency of convergence.
