Abstract
Research on language and identity has expanded considerably over the last two decades. Despite this expansion, the field remains theoretically diverse and methodologically fragmented. The present study provides a bibliometric review to map the intellectual structure, research trends, and scholarly influence within identity and language studies. Using bibliometric techniques, the study explores the relationship between author productivity and scholarly impact. Keyword co-occurrence and overlay visualization analyses are used to identify major thematic clusters and distinguish well-established topics from emerging or underexplored research areas. In addition, citation analysis is conducted to identify the most influential papers, while reference co-citation analysis is used to reveal the theoretical and conceptual foundations underpinning the field. The findings show that the higher number of papers does not necessarily lead to higher research impact. The keyword co-occurrence analysis reveals that identity and language research is organized around five interconnected thematic clusters, including sociolinguistic and ideological perspectives, bilingualism and heritage language, educational and professional identity, discourse and methodology-orientation, and psychological-affective dimensions of identity. As the overlay visualization shows, the emergence of topics such as teacher identity, professional identity, and agency reflects a growing concern. In addition, Norton (1995) and Heller (2003) are the most influential theories in the field. This study contributes to a deeper understanding of research trajectories and offers insights to guide future investigations on language and identity.
