民间文书是汉语词汇史和汉语词汇学研究的重要材料。从徽州契约文书材料中所见三组分别表示“推托”“怨悔”和“向上”义概念场的同义类聚材料出发,其每组概念场中的成员又可分成若干组并具有差异性义素。对徽州文书词汇的同义类聚现...民间文书是汉语词汇史和汉语词汇学研究的重要材料。从徽州契约文书材料中所见三组分别表示“推托”“怨悔”和“向上”义概念场的同义类聚材料出发,其每组概念场中的成员又可分成若干组并具有差异性义素。对徽州文书词汇的同义类聚现象进行研究的学术价值,表现在可以在此基础上进一步探讨民间文书词汇中同义类聚材料的丰富性、系统辨释同义词的同中之异的可操作性以及汉语词汇的系统性。Folk documents are important sources of information for the study of Chinese vocabulary history and Chinese lexicology. Starting from the three groups of synonymous vocabulary clusters found in Huizhou contracts, which respectively represent the conceptual fields of “delay”, “regret” and “upward”, it can be found that the members of each group of concept field words can be divided into several groups and have differential sememe. The academic value of studying the phenomenon of synonymous vocabulary clusters in Huizhou document vocabulary lies in the ability to further explore the richness of synonymous materials in folk documents, the operability of systematically distinguishing the similarities and differences among synonyms, and the systematic nature of Chinese vocabulary.展开更多
