苏皖交界地区吴语侯尤韵的读音及演变模式

The Pronunciation and Sound Changes of Rhymes Hou(侯)and You(尤)of the Wu Dialect in the Border Areaof Jiangsu and Anhui

苏皖交界地区吴语侯韵的读音有前元音型([ei]、[Y])、[i]介音型([iəu])和央元音+[u]韵尾型([əu])三种,尤韵的读音有单元音型[Y]、二合元音型[iu]、三合元音型[iəu]三种。侯尤韵的早期分合类型有[Y:Y]、[iəu:iəu]、[ei:iəu]、[əu:iəu]四种,它们是方言内部音变的结果,前两种属于殊途同归,第三种属于殊途异归,第四种属同途同归(主元音同),这四种类型均源自北部吴语共同的底层形式[^(*)eu:^(*)ieu]。苏皖交界地区吴语侯尤韵的读音呈现出层次叠置的特征,通过吴语内部不同读音类型之间的竞争,以及吴语和江淮官话之间的竞争,侯尤的读音呈现出复杂的混合型面貌。由于江准官话的强势地位,侯尤韵的音韵格局正在被[əu:iəu]分立型逐步替换。

In the border region of Jiangsu and Anhui,the Wu dialect exhibits three main types of pronunciation for the rhyme"Hou"(候):a front high vowel([ei]/[Y]);with a pre-nuclear glide[i]([iəu]);and with a coda-u following a central vowel([əu]).Similarly,the rhyme"You"(尤)has three pronunciation types:a monophthong([Y]);a diphthong([iu]);and a triphthong([iəu]).Early in the border region of Jiangsu and Anhui,there were four ways in which rhymes"Hou"(侯)and"You"(尤)were spitted or merged:[Y:Y],[iəu:iəu],[ei:iəu]and[əu:iəu].These variations resulted from internal sound changes within the dialect itself.The first two types represent different paths leading to the same outcome,while the third exhibits divergent outcomes,and the fourth follows the same path with the same outcome(sharing the same main vowel).All four types stem from a common substratum form of the northern Wu dialect[*eu:*ieu].The pronunciation patterns of rhymes"Hou"(侯)and"You"(尤)in the Wu dialect of the border region between Jiangsu and Anhui exhibit characteristics of stratified overlap.Through competition between different pronunciation types within the Wu dialect,as well as between the Wu dialect and Jianghuai dialect,the pronunciation of rhymess"Hou"(侯)and"You"(尤)manifests complex and mixed features.As a result of the dominant status of the Jianghuai dialect,the pronunciations of rhymes"Hou"(侯)and"You"(尤)in the Wu dialect of the border region between Jiangsu and Anhui are gradually being replaced by the[əu:iəu]type.
