隐喻是一种十分普遍的现象。它不仅是一种修辞手段,更是一种重要的认知和思维方式,与人们的生活密切相关。南北朝时期的墓志铭中有大量的同根词,这些词较多地采用了隐喻的方式构造委婉语,产生了一系列的新词。本文以南北朝墓志铭有关“坟墓”义的同根委婉语为研究对象,从隐喻的角度探讨了这类复音词产生的认知基础和思维方式。 Metaphor is a very common phenomenon. It is not only a rhetorical device, but also an important way of cognition and thinking, which is closely related to people’s life. The epitaphs of the Northern and Southern Dynasties have a large number of identical root words, these words are more metaphorical way to construct euphemisms, resulting in a series of new words. This paper takes the euphemism of the same root of euphemism related to the “tomb” of Southern and Northern Dynasties as the research object, and probes into the cognitive foundation and thinking mode of such polysyllabic words from the perspective of metaphor.
