从邪床禅在丹阳方言中的演变与历史层次

Sound Change and Historical Strata of Middle Chinese Initials “Cong”,“Xie”,“Chuang” and “Shan” in Danyang Dialect

中古的从、邪、床、禅几个声母的区别一直存有疑问。通过对位于江淮官话和吴语之间的丹阳方言的考察,以及丹阳与邻近几个方言点的对比,可探讨这几个声母在江淮官话和北部吴语一带的演变情况:其中,从、邪两母可推断出在某个时点是有区别的,但更早时可能有共同来源;而中古的床母、禅母在这一带则倾向于不分或相混。

There have been debates about the differences among Middle Chinese initials cong （从）, xie （邪 ）, chuang （床） and shan（禅 ）. The sound change of these initials in Jianghuai Mandarin and Northern Wu dialect can be observed by studying Danyang dialect located between Jianghuai Mandarin and Wu dialect areas and comparing it with some other dialects in the nearby areas. The initials cong and xie can be inferred to be different at some point of time, although they might have originated from the same source in earlier times. The two initials chuang and shan tend to be merged or mixed up in these areas.
