Thinking on the Development of Chinese Less Tone Mandarin Dialects
Some Chinese mandarin dialects have two-tone or three-tone patterns,which are different from the four-tone pattern of Putonghua,which are called less-tone mandarin dialects in this paper.Previous studies have discussed the reasons for the formation of such a tonal pattern,such as"Altaicization"caused by the influence of Altaic languages or the merging of different tonal values.This paper first di-vides Chinese less-tone mandarin dialects into two main areas:the northwest area and the Bohai Rim area,and then analyzes the reasons for the formation of the tonal patterns in these two areas respectively.It is believed that the external forces and internal adjustment mechanisms of language play a dominant role in these two areas,and some related issues are discussed.
