Fundamental Studies of the Grammar of Southern Ryukyuan dialects

我们已经描述了石垣的石垣方言、宫罗方言、西表的索内方言、宫古的多良方言和平良方言的格标记系统以及被认为是一种卡加里助词的“都”助词。考察其在石垣、平良、今归仁、首里四种方言中的功能，我们还指出，都助词具有焦点的功能，但不具有加贺助词的功能。通过对八重山方言中研究较少的西表方言语法的描述，我们掌握了八重山方言的大致轮廓。根据石垣方言动词的派生类型，对石垣方言的不及物动词和及物动词进行了分类，并得出了石垣方言动词与语态关系密切的结论。

We have described the case-marking system as well as the du particle, which has been said to function as one of the kakari particles, of Ishigaki dialect of Ishigaki, Miyara dialect, Sonai dialect of Iriomote, Tarama dialect and Hirara dialect of Miyako. Looking into its functions in the dialects of Ishigaki, Hirara, Nakijin and Shuri, we have also pointed out that the du particle functions as focus, but it does not as a kakari particle. By describing the grammar of Iriomote dialects, which have been understudied with compared to other dialects in Yaeyama, we have grasped a general contour of Yaeyama dialects. We also categorized intransitive and transitive verbs of Ishigaki dialect based on their derivational types and concluded that they have a close relationship with voice.
