本文利用认知语言学的语义范畴理论分析日语「し」类常用动词,阐释其类属划分以及家族相似性的组织性和规律性。同时,以人们来自客观世界的经验和认知事物的规律为基础,探析这类词原始模糊语义的产生、发展与习得的内在机制,从而建立以家族相似性为特征解释「し」类常用动词的语义网络。 In this paper, we use the semantic category theory of cognitive linguistics to analyze common Japanese “shi” class verbs, and explain their classification and the similarity and organization of the family. At the same time, based on the experience of people from the objective world and the laws of cognitive things, this paper explores the inner mechanism of the origin, development and acquisition of the primitive vague semantics of these words so as to explain the common use of the “family” The Semantic Network of Verbs.
