The loss of endangered languages has become an urgent international concern driven by globalisation, migration, and dominant-language policies. Although previous studies have explored revitalisation through community-based, educational, and technological approaches, existing research remains fragmented and lacks a large-scale empirical synthesis of global research patterns. This study conducts a bibliometric analysis of 1,214 peer-reviewed articles indexed in the Web of Science Core Collection using descriptive performance analysis, citation analysis, bibliographic coupling, and co-word analysis. The findings reveal the rapid expansion and interdisciplinary development of endangered-language revitalisation research, particularly after 2015, with increasing attention to cultural sustainability, Indigenous identity, multilingual education, and digital innovation. The Journal of Multilingual and Multicultural Development is identified as the leading outlet, while Kutlay Yagmur is the most productive author. The United States, Canada, and Australia dominate research output, while China shows rapid recent growth. The analyses identify major themes related to policy and pedagogy, Indigenous revitalisation, family language transmission, bilingual learning, and heritage identity. The findings also indicate a shift from preservation-oriented documentation toward community-centered revitalisation frameworks integrating sociocultural, educational, technological, and policy dimensions.
