Studies on the phonological properties governing grammatical processes of Japanese prosodic morphology

本研究项目试图揭示音系特性，这些音系特性作为控制日语韵律基础形态良好性的原则。因为绝大多数日语韵律形态出现在模仿词汇和外来词中，所以我主要研究了这两个词汇类别中观察到的形态-语音过程。基于在生成音系学框架下发展起来的一些理论概念，我发现了许多有趣的音系机制，这些机制隐藏在各种类型的现象之下。特别是，我对约束互动的机制进行了深入的研究，它对输出形式的语法评价产生了深远的影响。作为调查的主要结果，我发现了一个显著的趋势，即在日语中，无标记结构绝对是各种基于韵律的形态学的最佳输出模式。这完全符合最近在最优性理论中发展出来的理论结果。

The present research project attempts to shed light on phonological properties which serve as principles controlling the well-formedness of prosody-based morphology in Japanese. Because a large majority of Japanese prosodic morphology appears both in mimetic vocabulary and in loanwords, I have mainly examined the morpho-phonological processes observed in these two lexical categories. Based on some theoretical notions developed in the framework of generative phonology, I discovered quite a few interesting phonological mechanisms underlying various types of phenomena. In particular, I did an in-depth investigation of the mechanism of constraint interaction, which exerts a profound effect on grammatical evaluation of output forms. As the main result of the inquiry, I found a notable tendency that unmarked structure is definitely favored as an optimal output pattern of various kinds of prosody-based morphology in Japanese. This is in full accordance with recent theoretical results developed in Optimality Theory.
