文章以古微母及影疑母开口一二等字在近现代北京话中的声母演变轨迹为例,讨论汉语中存在的“逆向音变”现象。从近代史料中可以看到,微母[v]和疑母[]在北京话中都曾完成向喻母或影母的合流而改读零声母,但合流后的部分喻微母字或影疑母字在当代出现了或在早些时候可能出现过向[v]或[]声母的逆向音变,在此基础上文章初步归纳了逆向音变的一些基本特点。 This paper takes the evolution of the initials of the ancient mom and the shadowy suspect in the dialect of the modern Beijing dialect as an example to discuss the existence of the “reverse phonetic” phenomenon in Chinese. It can be seen from modern historical materials that both mother [v] and suspect [] have completed the conversion of the zero initials to the confluence of the mother or the shadow parents in Beijing dialect. However, On the basis of this, some basic characteristics of reverse sounding are initially summarized in this paper.
