Outline of Final Research Achievements

I studied information structure of Tokyo Japanese and Tohoku dialect. In Tokyo Japanese, I studied how information structure is expressed in particles, word order, and intonation. In Tohoku dialect, which often lacks particles, how different information statuses of a constituent is expressed in different constructions. I and colleagues also published databases of Hatoma dialect and Okinawan, and some papers on phonology of Noheji Dialect, Aomori, and Shiraho dialect, Yaeyama Ryukyuan.

Academic Significance and Societal Importance of the Research Achievements

日琉語族の情報構造表現の変異を記述することにより、同じ語族の中でどのような表現の可能性があるのか、ある類型論的特徴(e.g., 助詞の頻度が低い)が情報構造の表現を制約する可能性を明らかにした。
また、消滅の危機にある言語の大規模なデータベースを作成して公開することで、継承話者の学習に役立つ、フィールドワークに行かなくても研究できるデータを広く一般に提供した。
