作为人类认知体验的成果之一,语言本身就具有模糊性。模糊性是语言的基本属性。虽然模糊语义界限不明,人们仍然能够运用模糊语言成功地进行交际,这与人们的认知是分不开的。从认知角度可剖析人们是如何运用范畴化以及原型理论对模糊语义进行解构从而达到理解的大致一致。 As a result of human cognitive experience, the language itself is ambiguous. Fuzziness is the basic attribute of language. Although ambiguous semantic boundaries are unknown, people can still use vague language to communicate successfully, which is inseparable from people’s cognition. From the perspective of cognition, it is possible to analyze how people use categorization and how prototyping deconstructs fuzzy semantics so as to achieve broad agreement on understanding.
