Multi-angle Analysis On Causal Conjunction ’Yin’er’

"Ym’ er" is an important causal connective of the modern Chinese conjunctions, the research on "Yin’er" will help to grasp the characteristics of the causal connectives from the microscopic point of view. This dissertation studies the specific features of "Ym’er" on lexicalization, syntactic, semantic and pragmatic, then compares it with the other similar conjunctions "Yinci, Cong’er", finally, analyzes the reasons and put forward the teaching suggestions based on the biased errors when the foreign students use "Yin’ er, Yinci, Cong’er". This paper includes these parts:Part one is the chapter one introduction. In this part, we will determine the study subject of this paper is the common causal conjunction "Yin’er", in the research content, we will study the process of becoming a word, the features on syntactic, semantic and pragmatic, the differences from the other conjunctions and the biased errors, then point out the significance of this research and the commentates of domestic and foreign. Lastly we illustrate study methods used in the paper and where the databases come from.Part two is from chapter two to chapter four, it is the core content of this paper. Chapter two will study the lexicalization process of "Yin’er" by researching the semantic grammar evolution of "Yin" and "Er" under diachronic and synchronize methods.
