A Theoretical Framework for Understanding Igbo Language Revitalisation in the Twenty-First Century: Integrating Ecology, Agency, and Policy

This study develops an original theoretical framework for understanding and planning Igbo language revitalisation, integrating insights from language ecology theory, language agency perspectives, and language policy analysis into a coherent, Igbo-specific conceptual architecture. Existing revitalisation theory has been largely derived from the experiences of European minority languages and indigenous languages in settler-colonial contexts, creating a theoretical alignment problem when applied to major West African languages such as Igbo that occupy a demographically large but institutionally marginalised position. The theoretical development is grounded in a systematic review of over two hundred peer-reviewed publications on language revitalisation, ecology, and policy published between 2018 and 2024, combined with thirty elite interviews with Igbo language policymakers, academics, and community leaders across six geopolitical zones. The resulting framework, designated the Igbo Language Revitalisation Ecology model, identifies five interacting domains: demographic vitality, institutional embedding, agency activation, digital ecology, and policy coherence. The model is tested against historical case studies of four partially successful Igbo language revitalisation initiatives from 1980 to the present. Findings confirm that single-domain interventions consistently fail to produce sustained revitalisation outcomes, while coordinated multi-domain initiatives show evidence of ecosystem-level language system stabilisation. The study makes an original contribution to revitalisation theory by introducing the concept of culturally specific revitalisation agency as a mediating variable absent in existing frameworks.
