| Outline of Final Research Achievements |
The purpose of this study is to identify the social factors contributing to the linguistic decline of the Okinoerabu language on Okinoerabu Island, located in the Ryukyu Islands, Japan, through linguistic experiments and interview surveys. During the study period, a qualitative survey involving interviews with 26 participants and a quantitative survey involving questionnaires completed by 505 participants were conducted. The analysis focused on various factors, including education on dialect prohibition, dialect use at school, work, with friends, and at home, media influence, language choice within the household, changes in marriage partner selection, language awareness, and language transmission activities. The results indicated an association between the age of rapid decline in Okinoerabu comprehension and the age at which parents and other household members (e.g., older siblings) began using the standard language at home.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の学術的意義は、危機言語の言語衰退の実態と、その背後にある言語選択の変化の関連を、言語実験・インタビュー調査・アンケート調査から実証的に明らかにした点である。本研究の過程で行われたアンケート調査は、沖永良部島における初めての言語意識調査であり、資料的価値が高い。また、本研究は(a)言語衰退と直接関連がある要因を導いた、(b)島内の言語意識の実態を把握した、(c)危機言語の学習意欲がある人の学習ニーズの実態を捉えられた、という点において、現在島内で行われている言語復興・言語継承活動の基盤となるデータを提供し、今後の言語継承活動に貢献できると考えている。
