喻四归匣——古以母演变的另一形式

The Merger of Initial yi and xia: Another Form of Evolution of Initial yi

喻三(云母)上古归匣,中古以后,喻三与喻四(以母)合并为j-,并向零声母演变,这已是汉语音韵学史的定论,也得到大多数现代汉语方言的支持。但在东南方言,古以母的演变似有另一种形式:以母归匣,并与云母、匣母四等一同向j-(或零声母)演变。本文尝试对这一语音现象作一些探讨。

The fact, that initial yn (喻三) having belonged to initial xi?(匣)in ancient time whereas merged into j- with initial yǐ(喻四) and then evolved toward zero , has been a final conclusion, and it has also been supported by the majority of the Chinese dialects. But it seems that the ancient initial yǐ goes under another way in the southeast Chinese dialects. That is to say, initial yǐ had merged with xi?(γ→h)and then evolved toward j-(or ) together with initial yn and forth division of xi?.
