通泰方言的小称变调残迹

摘要

In Tongtai dialects,there exists a special word-ending tone sandhi,which means the last syllable of certain polysyllabic words read the third tone regardless of its original tone.This paper first describes this phenomenon taking Rugao(Taoyuan)subdialect as the example.Then illustrates its geographical distribution.Finally discusses the attribution of the tone sandhi,suggesting that it is the relic of the diminutive tone sandhi which was broadly distributed in early Tongtai dialects.Be-sides,the paper attempts to demonstrate that the condition of its formation is not the modern suffix“er”(儿)but the historical nasal suffix characteristic of the “er”ending.%通泰方言中存在着一种特殊的词末变调现象，即部分多音节词的末字不论其单字调为何一律读作同上声一样的调值。文章首先以如皋(桃园)话为例对这一现象进行共时描写，然后考察它的地理分布状况，最后讨论其性质，认为词末变调是通泰方言早期小称变调的残迹，并指出它形成的基础不是现在的儿尾，而是历史上的鼻音儿尾。
