A Study On The Evolution Of "Disease" Words From Pre Qin To Han Dynasty

In this paper,synchronic and diachronic methods,quantitative and qualitative analysis,combined with corpus reference dictionaries,are used to study the evolution of "disease" words from pre Qin to Han Dynasty.This paper selects the representative documents from Pre-Qin to Han Dynasty and combines them with corpus.We take the word "disease" as an example,according to the diachronic corpus of the target words,we divide the meaning items with unified standard and logical structure.The meaning items of the word "disease" are different in the same,and the collocation,context and corresponding grammatical function of the same meaning items are also different in the same.From these four aspects,we distinguish the "disease" words from the pre-Qin to the Han Dynasty.The main body of the paper is divided into five parts:The first part(the first chapter)is the introduction,which mainly introduces the reason,the research history and the present situation,the research method and the research significance.In the second part,we choose three target words and put forward the principle of meaning division.We set up the meaning of "disease" in Chinese from Pre-Qin to Han Dynasty,and connected the extended context of each meaning.In the process of sorting out the extension context of "disease" words,we found the relative extension and cross meaning extension rules of similar words.In the third part,we distinguish the "disease" words from the meaning,context and collocation.In the fourth part,we collected,sorted and marked 2757 corpora from 36 documents in the two periods of pre Qin(Zhou,spring and autumn,Warring States)and Han(Western Han,Eastern Han),and distinguished the grammatical functions of the meanings of "disease" words.In the process of tagging the corpus,we also mark the grammatical function of the target word,until the minimum structure of the target word exists,and observe the similarities and differences of the grammatical function of the same meaning.The last part of the paper summarizes the similarities and differences of the grammatical functions of the same semantic items of the "disease" words,analyzes the phenomenon of the replacement of the new and old words of the "disease" words,and investigates the situation of the replacement of the "disease" words.
