转喻和隐喻是英汉语中两种重要的修辞格,由于二者均涉及词义的转化,因此,两种修辞格容易混淆。作者在阐述转喻和隐喻两种修辞格定义及类型的基础上,利用认知语言学的理论,提出了转喻和隐喻两种修辞格的四条判定规则。 Metonymy and metaphor are two important figures of speech in English and Chinese. Because both involve the conversion of word meanings, the two rhetorical figures are easily confused. Based on the definition and types of metonymy and metaphor, the author makes use of the theory of cognitive linguistics to propose four rules for the determination of metonymy and metaphor.
