On the Subjective Extremity Construction of “X Dao Buxing”

结构“X到不行”是人们平常使用较多的一种表示主观极量义的表达。文章从语义、语用、构式义、形成机制这几个角度分析构式“X到不行”的主观极量义如何体现、如何产生的。语义上，构式表主观性和主观极量义，语用上，构式具有主观极性评价、超预期表达、求新求异的用法；结构“X到不行”的构式义浮现机制为构式互动。The construction “X Dao Buxing” is a prevalent linguistic pattern in Chinese for expressing subjective extremity. This study investigates its semantic, pragmatic, and constructional features to reveal its mechanisms of meaning formation. Semantically, the construction encodes subjectivity through semantic bleaching, while pragmatically it serves three functions: extreme evaluation, counter-expectation marking, and discourse innovation. The meaning emergence of “X Dao Buxing” stems from constructional interaction.
