利用认知语言学的语义范畴理论对日语「お」类常用动词进行认知分析,说明「お」类常用动词的范畴化、家族相似性以及模糊语义的组织性和规律性。并且以人们的客观世界经验和认知事物的规律为基础,探讨「お」类常用动词原始模糊语义的产生、发展与习得的内在机制,从而建立一个解释「お」类常用动词以家族相似性为特征的模糊语义网络。 Cognitive analysis of common Japanese verbs using the semantic category theory of cognitive linguistics illustrates the organization and regularity of categorization, family similarity and fuzzy semantics of commonly used verbs. And based on the laws of people’s objective world experience and cognition, this paper explores the internal mechanism of the generation, development and acquisition of the original vague semantics of the common verbs in order to establish a family of similar verbs Sex - oriented fuzzy semantic network.
