认知语言学为词汇语义的衍生提供了重要的理论依据。本文从认知视角对“火”的情感语义进行了深入研究,主要研究结果为:1.“火”的情感语义范围涵盖了喜怒等基本情感,尤其体现在以人体器官来表达“火”的愤怒义;2.“火”的悲伤和恐惧情感语义在语料上没有得到体现。本文认为这些现象是由于人们的身体经验、认知所致;隐喻和转喻是“火”情感语义最主要的衍生与扩展机制。 Cognitive linguistics provides an important theoretical basis for the derivation of lexical semantics.

This paper argues that these phenomena are caused by people’s physical experience and cognition. Metaphor and metonymy are the most important derivation and extension mechanisms of the emotion sentiment of “fire”.
