粤北地区的汉语方言十分复杂 ,我们把当中的一群归属未明的方言土语统称为“粤北土话”。本文根据粤北 1 0个县 (市、区 ) 2 4个土话点的材料 ,归纳出中古全浊声母字在粤北土话中今读清塞音、清塞擦音时送气、不送气的类型。在 5种类型中 ,我们认为有 3种类型是汉语方言中比较罕见的 ,这些类型对于汉语方言乃至汉语史的研究都具有一定的参考价值。 The Cantonese dialects in northern Guangdong are very complicated. We refer to them as a group of untouchable dialect natives called “Dialect of Northern Guangdong.” Based on the data of 24 earthy points in 10 counties (cities and districts) in northern Guangdong, this paper summarizes the types of airborne and non-aspirated airways in the ancient Cantonese dialect of the Middle Eastern voiced initials. Among the five types, we think three types are relatively rare in Chinese dialects. These types have certain reference value for the study of Chinese dialects and even Chinese history.
