作为一个在生成音系学基础上发展起来的语言学理论,优选论在语言变异研究中也得到了应用。但是,现有的语言变异的优选论语法模型都还存在着不同程度的问题。针对这些问题,本文提出一个新的优选论模型,该模型继承了优选论中制约条件层级性和语法相对性的思想,同时允许输出项之间的层级性变异。在理论层面,该模型将语言变异解释为语法的“实现度”。结合“实现度”的新优选论模型通过北方话鼻韵尾变异的现实语料得到了验证。
As a linguistic theory developed on the basis of phonology, the theory of preference has also been applied in the study of linguistic variation. However, there are still some problems with the existing optimization models of language variation. In response to these problems, this paper presents a new optimization theory model, which inherits the idea of hierarchy of constraints and the relativity of grammar in the optimization theory, while allowing the hierarchical variation between output items. At the theoretical level, the model interprets linguistic variation as the “degree of fulfillment” of grammar. The new optimization model combined with “degree of achievement” is verified by the corpus of the northern dialect variation.
