由原型理论看英语词义变化机制

在语言这个科学系统中，词汇是最活跃、最具可变性的一部分。长期以来，词汇结构并不是词汇变化的主要方面，因而研究词义变化就显得尤其重要。运用原型理论来探究词汇领域稳定性与灵活性并存的现象，能够更好地分析出词义变化机制。这对英语的词汇学习有一定启示。

The Change of Lexical Meaning from Perspective of the Prototype Theory

In the big system of language, lexicon is the most active and flexible part. For a long time, the lexical structure is not the major aspect of lexical changes, therefore, a study of the change of the lexical meaning accounts to be especially important. This paper explores this problem from the cognitive perspective by the famous prototype theory to explain the coexistence of stability and flexibility within the lexical field. When studying the change of the lexical meaning, we hope that this paper can also shed some light on English lexicon learning.
