从“港”字的读音看语言的社会属性对语音的影响

From the Pronunciation of"港"Talking about the Influence of Language Social Nature on Sound

"港""讲"二字,中古完全同音,但"讲"字腭化了,"港"字却没有腭化,对此,许宝华和潘悟云两位先生认为是由于中古介音--的发展趋势不同。笔者认为它们所"受发音生理的制约"应该是一样的,这种不规则的音变现象除了受其本身语音条件的制约之外,还应该受到了其他音变因素的影响,其中最主要的当是语言的社会属性对语音的影响。

'讲'and '港' are homonyms in the middle ancient times,but '讲' has already 'a hua',yet '港'hasn't.To the phenomenon,Xu Baohua and Pan Wuyun hold that they are different in the sound change because of differently developing trendency of middle ancient vehicle.But I think that they are same in the aspect that they are limitted by the pronunciable physiology.This kind of abnormal phonetic change is not only restricted by their own phonetic terms,but also is influenced by other factors of phonetic change,among which the most important factor is the influence of language social nature on sound.
