The Dunhuang Change The Text Allotropy Word

As a special type of compound words,Tong-su-yi-xu words has been researched for a lot.Some of them aimed at the different language times,such as vernacular time,middle ancient time,early modern time and modern time.The others payed attention to a special book.In one word,the research before always did like that:analyzed some words or do research from one aspect,so they were not overall enough.This thesis chooses 257 groups of Tu-su-yi-xu words from Du-huang Bian-wen and do more detailed and considerate analysis to them.Above all,I desperate them from meaning,and there are five types.They are the same meaning,the similar meaning,the contained meaning,the crossed meaning and the different meaning.After that I desperate them from structure,and there are eight types.By my investigation from these two aspects,I find that most groups of Tu-su-yi-xu words in Bian-wen have the same meaning and the words with coordinate structure have a high proportion.The quantity of other type is very small.Then I investigate why these Tu-su-yi-xu words come up in Dun-huang Bian-wen,and I think there are three main reasons:first,a lot of compound words appeared in that period;second,the need of thetorical function;third,in order to express more exactly.We can say that although Du-huang Bian-wen is a kind of oral literature,its librettoes are full of ryhthm and its buddhist story can give us much education,these all accelerate the appearace and application of Tong-su-yi-xu words in Bian-wen.At last,I research whether the Tong-su-yi-xu words exist in mordern Chinese and which rules they follow.By this research I find that only a few groups of Tong-su-yi-xu words in Bian-wen both exist or disappear in modern Chinese,to most groups of them,one word exists and the other word disappears.This is the demand of simplication of language,and it is good to our communication.It is sound,meaning and our habit which make the choice of one word.By quantitative and qualitative analysis,This thesis analysizes the Tong-su-yi-xu words in Bian-wen from above aspects,and I hope to have an overall understanding of the characteristics of Tong-su-yi-xu words in Bian-wen.
