量词定指现象在东亚和东南亚的语言中并不罕见。我国境内的吴、闽、粤、客家、赣、湘等南方汉语方言中也存在着这一现象。在有关这一现象的诸多可能性来源中,“语言接触说”最能实现解释的简约性。同时这一推论也得到了来自音韵学、文化学、考古学、民族学等方面的佐证。我们还以桂南平话和壮语的接触为例,重点关注了平话中量词定指现象的来源。 It is not uncommon for quantifiers to be defined in the languages ​​of East and Southeast Asia. This phenomenon also exists in the southern Chinese dialects of Wu, Min, Yue, Hakka, Gan and Xiang in our country. Among the many sources of possibilities for this phenomenon, the “language contact theory” most often achieves the simplicity of interpretation. At the same time, this corollary also got evidence from phonology, culture, archeology and ethnology. Taking the contact of Guiping dialect and Zhuang language as an example, we focus on the source of quantification in Ping dialect.
