【摘要】 本文讨论附着在句尾的"不是"的来源、语用功能及其词汇化问题。研究表明,附着在句尾的"不是"是核心功能表示确认的情态性成分,来源于"是……不是"肯否相叠结构,其源头是"是NP不是NP"正反问框架。"是……不是"正反问框架消解,句尾"不是"语音轻化、表态功能突显、尾部脱落引发的重新分析以及"是"的进一步虚化共同促成"不是"词汇化,但其深层动因是语用法的语法化,突出表现为"不是"在使用过程中互动性逐渐降低。更多还原

【Abstract】 This paper focuses on the problem of the source,the function and lexicalization of the sentence-final bushi(不是).Bushi is a modality word,whose core function is to declare confirmation.It evolved from the overlapping positive and negative structure of shi…bushi,and originated fromshi NP bushi NP.The lexicalization of bushi was caused by the dissolution of the shi…bushi structure,the unstressed sentence-final bushi,the highlighted declaration of confirmation,the reanalysis caused by the missing sentence-final,and the further grammaticalization of shi.But the deep motivation is the grammaticalization of pragmatics of bushi,which is especially manifested by the decreasing interactive nature of bushi.更多还原
