閩語白話音分支時代考

DERIVATION TIME OF COLLOQUIAL MIN FROM ARCHAIC CHINESE

在古音研究的領域裡，漢語方言的資料主要用於隋唐中古音的討論，很少作為擬測周秦上古音的印證。因為各大方言從古漢語方歧出的時間大致均在中古音之後，方言中語音變化的種種現象大致都能利用中古音系來解釋。惟一的例外是閩語，由於近年來的研究，使人確信閩語的白話音在中古音之前已經從古漢語中分出來了，很可能在漢代前後，而確切的時間因為證據不足而不敢說定。

In the field of Chinese_ historical phonology, dialectal material has been utilized chiefly for the reconstruction of Ancient Chinese (from about A.D. 600), but rather rarely for the reconstruction of Archaic Chinese, the language of roughly the first millennium B.C. The reason for this is quite dear, because most dialects derived from the main stream of the Chinese language after the sixth century, and phonological changes of these dialects can be well explained by the system .of Ancient Chinese. The only exception is colloquial Min which had definitely branched off before the period of Ancient Chinese, but the exact time has not been determined. It is the purpose of this paper to clarify this point.
