Morphological and Prosodic Structures in Tahltan

这项名为《Tahltan的形态和韵律结构》的博士后研究将调查Tahltan(北部阿萨帕斯坎)两种方言的重音，并将导致关于形态结构和韵律结构相互作用的可检验假设的发展。韵律分布的重音和对单词的二元性要求表明韵律脚在定义单词结构中起到了作用。该词的韵律结构也与词形重音的分析有关。在一种方言中，词干总是重读的，至少可以用两种方式来接近。在一种假设中，重音分配可以获得形态结构，因此重音脚可以直接分配到词干；在另一种假设中，形态信息仅被间接引用，规则的词干应力来自于词干和韵律词的排列。本文勾勒出一条调查路线，将这两种方法在经验基础上加以区分。这一分析引出了一系列的经验和理论问题，包括重音在具有一个以上固有重音的词中的实现，复合词和动词屈折变化的分析，以及一种方言中常规词干重音与另一种方言中词汇词干重音之间的历史关系。

This research post-doctoral fellowship, entitled, "Morphological and Prosodic Structures in Tahltan," will investigate the stress in two dialects of Tahltan (Northern Athapaskan), and will lead to the development of testable hypotheses concerning the interaction of morphological and prosodic structure. Rhythmically distributed stress and binarity requirements on words suggest a role for the prosodic foot in defining word structure. The prosodic structure of the word is also implicated in the analysis of morphological stress. In one dialect, the morphological stem is always stressed, which may be approached in at least two ways. On one hypothesis, stress assignment has access to morphological structure, and so stress feet may be assigned directly to the stem; on another hypothesis, morphological information is only indirectly referenced and regular stem stress follows from the alignment of the stem and the prosodic word. A line of inquiry is sketched which will distinguish these two approaches on empirical grounds. This analysis leads to a host of empirical and theoretical questions regarding the realization of stress in words with more than one inherently stressed morpheme, the analysis of compounds and inflected verbs, and the historical relationship between regular stem stress in one dialect and lexical stem stress in another.
