Abstract This paper presents a cross-linguistic survey of non-local allomorphy and it develops a formal model that accounts for the observed patterns. The distance between the trigger and target of allomorphy in non-local patterns is much more conservative than expected. A model of Vocabulary Insertion is developed, where the limited distance follows from the basic linear computational properties of the PF-interface.

约束远距离同构

摘要本文提出了一种非语言同种异体语言的跨语言研究，并建立了一个解释观察模式的正式模型。非局部模式中同种异体的触发器和目标之间的距离比预期的保守得多。建立了词汇插入模型，其中有限的距离遵循PF接口的基本线性计算属性。
