西北方言全浊清化的年代考

On the Time of the Voiceless Coming from the Complete Voiced in Northwest Dialects from the Pronunciation of Toponym

地名读音完好地保留了方言的历史读音,是研究方言史的活化石。通常认为西北方言全浊清化的的时代是唐五代,但根据韵书和文献中的地名推算,西北方言全浊清化的时代可上朔至南朝。

The pronunciation of toponym, which remains the historic pronunciation quite well, is the active fossil of dialectology. It is generally estimated that the time of the voicing of the complete voiced in northwest dialect is Tang and the Fifth Dynasty, but it goes back to the South Dynasty according to the rhyming dictionary and some documents.
