“美哭”类流行语是位于动结型致使合成词“V哭”和“形容词+程度补语”之间的独特新生结构,其内部组合在语义构造、组合机制、修辞功能、产生理据等方面均具有一定特殊性。本文通过分析“美哭”类结构的语义解读路径和产生动因,进一步探讨由“美哭”衍生出的系列程度补语的夸张修辞机制。研究发现此类新兴补语表达的核心概念为极致义,主要修辞功能为程度夸张,同时带有基于言说者主观审美经验的情感宣泄,探讨流行语创生过程中语言经济性原则和元语言认知驱动作用,在一定程度上解释了现代汉语“乖戾”构词背后的认知动因,为新词构成机制和发展趋势的深入研究提供了一些思考。 “Melody ” type buzzword is a unique newborn structure which is located in the conjunctive type that causes the syntactic word “V cry ” and “adjective + degree complement ”.
