2008年下半年以来,网络及报刊杂志上出现了一大批含“雷”字的新词语。本文在考察“雷”族新词用法的基础上,从原型范畴理论的角度,探讨了它对已有的汉字“雷”的词义扩大以及它的词类转换机制,并用词语模框架理论阐释了其发展壮大机制。“雷”族新词的产生和发展不仅是一种语言现象,本文还分析了它折射出的多种社会文化心态。 Since the second half of 2008, a large number of new words containing “Lei” have appeared in the internet and in newspapers and magazines. On the basis of examining the usage of new words in the “Lei” family, this paper discusses the expansion of the meaning of the existing Chinese characters “Lei” and its part-of-speech conversion mechanism from the perspective of prototype category theory. Theory explains its growth and expansion mechanism. The emergence and development of “Lei” new words is not only a linguistic phenomenon, but also analyzes the various social and cultural attitudes it reflects.
