隐喻是一种象似符。隐喻借助于自己的特征指示事物,即通过描述其他事物中的对应关系来体现事物的表象特征。皮尔斯认为,符号具有“三位一体”性质并具有层级性。作为一种特殊的语言符号,隐喻也具有这些性质。本文应用皮氏符号学理论,分析了网络隐喻符号的“三位一体”性质和层级性,从一个新的视角理解隐喻,同时也是对皮氏符号学理论的实践。 Metaphor is an iconic character. Metaphors use their own characteristics to indicate things, that is, by describing the correspondence between other things to reflect the appearance of things. Pierce believes that the symbol has the character of “Trinity” and has the character of hierarchy. Metaphors also have these properties as a special linguistic symbol. In this paper, Pearson’s semiotic theory is applied to analyze the nature and hierarchy of the “Trinity” of metaphorical symbols in the network. From a new perspective, metaphors are understood and the practice of Pee’s semiotics is also studied.
