西北方言入声韵带i介音现象

The i-Medial Phenomenon of Entering Tones in Northwestern Dialects

西北方言曾开一入(德韵)、梗开二入(陌麦韵)今带i介音这一特征,主要分布在兰银官话的银吴片、河西片,以及中原官话陇中片的民和、乐都两县。它们的共同特点是曾摄德韵和梗摄陌韵、麦韵字今韵母合流。通过同山西方言入声韵的比较,发现这一特征属于外源性层次,是山西方言影响的结果。

Northwest dialects have the feature of Zeng and Geng rhymes with first and second entering respectively with i-medial. The primary distribution is Yinwu fraction, Hexi fraction of Lanyin mandarin as well as Minhe and Ledu counties of the Gansu fraction which belongs to central China mandarin. Their common characteristics are the mergers ofZeng, Geng and Ru rhymes as well as the in- tegration of rhyme Mai with current finals. Through a comparison with Ru rhyme of Shaanxi dialect, it is found that this feature belongs to exterior origin level, which is a consequence of Shaanxi dialect.
