浙江義烏話的[n]尾韵及其音變

浙江義烏話[n]尾韻相當于北京話的兒化，其音變形式是：刪除原音節的韻尾，加上[n]，韻腹有變化，并且元音變長，如“瓶兒”。元音音變是規則的。本文從義烏話單音節加[n]尾所引起的音變入手，提出：一，所引起的音變由刪除原韻尾而產生，后綴音節[n]并沒有直接引起詞根音節的元音變化；二﹐這種現象不是原音節的“n”化，而是詞根音節加上后綴音節[n]構成的復合音節。本文用優選論對義烏話[n]尾韻音變的解釋作了簡單評述。
The [n] ending final in the Yiwu dialect, in correspondence with -r suffixation in the Beijing dialect, features the deletion of the final of the original syllable and adding the ending [n]. It involves the changes in nucleus and extension in vowel. The phonetic change of its vowel is regular. The author puts forward that 1) the phonetic change is caused by the deletion of the original ending rather than by the vowel change in the root syllable directly led by the adding of [ n ], and 2) such phenomenon is not suffixation, but a compound syllable by adding the final[n]to the root syllable. The article also gives a simple account on such phonetic change using the optimal theory. Copyright © 2002 中國社會科學院語言研究所.
