A Critical Lexical Ecology Model for Indigenous Language Preservation in Nigerian Educational Environments

The rapid modernization of Nigeria's educational systems has led to a significant shift away from indigenous languages in favour of English and other foreign languages. A comprehensive literature review method was employed to identify key linguistic features essential for effective language preservation strategies in educational contexts. The proposed model integrates these insights into an educational toolkit designed to integrate indigenous language preservation into mainstream curriculum development processes. Educators and policymakers should prioritise the integration of this lexical ecology model in curricula design to enhance linguistic diversity and cultural continuity.
