本文目的是分析关中方言果摄字读音的历史层次。从共时平面看,关中方言果摄字读音根据主元音的不同可归纳为两类:①以[a]及其变异形式为主元音;②以[o]及其变异形式为主元音。这些读音有的以音类为分布条件,有的则以语素为分布条件。从历时角度看,这些读音差异实际上反映了语音发展的不同历史层次,有的是滞古层次,有的属后起变化;其变化既有连续性音变方式,也有词汇扩散方式。 The purpose of this paper is to analyze the historical level of Guanzhong dialect and its pronunciation. From synchronic plane, the pronunciation of Guanzhong dialect can be classified into two categories according to the difference of the main vowels: (1) The main vowel is [a] and its variation; (2) The main element is [o] and its variant sound. Some of these pronunciations are classified as phonetic while others are morphemes. From diachronic perspective, these differences in pronunciation actually reflect the different historical levels of phonetic development, some of which are lagging behind and some of them change from the latter. Their changes include both continuous phonetic transcription and lexical diffusion.
