An Analysis To The Cognates From Yang-Rhyme Of Tong-Group And Jiang-Group In Guang-Yun

The problem of cognates is an important content in the research of the Chinese language history. Extensive researches in cognates will help us to reveal the systematicness of Chinese vocabularies. The thesis regards modern etymology academic theories theory as to guide. Appling various methods ,it studies the cognates from Yang-rhyme of Tong-Group and Jiang-Group in Guang-Yun. After the analysis to the cognates' kernel-lexeme(核义素) and the verifications with literature materials, we can find out the combining regulation of the sound and semantic. It has certain theoretical and practical significance in establishing an tide Chinese vocabulary system.The thesis is composed of three parts:Chapter one is preface.It mainly states some information, for instance,why to select the question for study, what achievement have been reached at present, how to select the materials for study,what kind of theories and methods to use and what a conclusion to draw. Chapter two is the analysis to the cognates from Yang-rhyme of Tong-Grade and Jiang-Grade in Guang-Yun. Unit 1, a general reach in Chinese etymology; Unit 2,About cognates.Firstly, the definition of cognate .After some contrast , the thesis made a definition "cognate is a kind of word which dirive from the same etymology and have similar sound and correlative meaming".Secondly, the basis of judging cognate;Unit 3, the analysis to the cognates from Yang-rhyme of Tong-Grade and Jiang-Grade in Guang-Yun. After investigating 240 cognates' kernel-lexeme, and verifing these words with literature materials, the thesis divides them into 40 groups.Chapter three is the analysis to the sound's characteristic and the semantic characteristic of these cognates.After the comprehensive analysis to these 40 phrases , the thesis make a summary of these words in two kinds. Firstly, the type of sound' relationshipship.It includes 6 types : sound alike; sound similar; sound changed; sound alike and sound similar; sound alike and sound changed; sound alike sound similar and sound changed; Secondly, the type of semantic relationshipship. It includes 7 types: the first is possessing the same quality; the second is possessing the same feature; the third is general reference and particular reference; the fourth is behavior and object ,the fifth is reason and result; the sixth is abstract and concrete; the seventh is complex relation.On the base of it , we testify that the combining regulation of the sound and semantic is sound similar and semantic coherent .That is to say, the word with the same xiesheng-phonetic sign(谐声声符) often has the coherent semantic .It is thus clear that we can connect the cognate group xiesheng-phonetic sign .The last part of the thesis is conclusion . The achievements that the thesis obtains and the direction for studying in future are briefly described .The thesis has three main characters : firstly, beacause it occupies abundant character material(1132 Chinese characters all together), some cognate group has a lot of members.It almost reaches 20 cognates. Secondly, It respects the historical fact.There are a lot of literature materials in studing, which make an authentic and correct result ;Thirdly, the thesis conclodes some law about the cognate's sound and semantics .The law can suits to the other scholar's point , that make the research authentic and correct.
