冀鲁官话果摄一等字韵母读音历时演变研究

Study on the Diachronic Evolution of the Pronunciation of Guoshe(果摄)in Jilu Mandarin

从中古到现代,冀鲁官话中果摄一等字的语音演变主要表现为元音高化,开口呼舌齿音u介音的增生,合口呼牙喉音u介音的脱落以及见系韵母展唇化。通过考察历史文献材料与现代方言材料,可以发现,u介音的增生与脱落均是由于声韵之间发音动程所导致的,其目的是为了发音连贯性。见系韵母展唇化在冀鲁官话中是一种自身演变,其演变动因是声韵异化。果合一牙喉音韵母uo>ɤ/ə的演变不晚于19世纪中期。

The phonetic evolution of the Guoshe(果摄)character in the Jilu Mandarin dialect from the Medieval period to the modern dialect is mainly manifested in the vowel elevation,The proliferation of tongue-dental u-medium,Loss of the vowel u of the guttural vowels and the lip extension of vowel of Jian Xi(见系).By examining historical documents and modern dialects,the proliferation and shedding of the u-medium sound are caused by the pronunciation movement between the phonology and rhyme.In Jilu Mandarin,the lip-extension of Jian Xi(见系)vowels is a kind of self-evolvement,and the motive of the evolution is to ensure the coherence of pronunciation and the alienation of phonological rhyme.The evolution of the vowel uo>ɤ/əin the Guoheyi(果合一)tooth throat is no later than the middle of the 19th century.
