Abstract
Indigenous languages are essential for attaining national healing and sustainable development. Their revitalisation promotes identity, intergenerational healing, governance inclusion, enhanced health and education outcomes, and economic empowerment. This research examined the significance of indigenous languages in the context of national reconciliation and development. The study utilised a descriptive survey design to evaluate Nigerian residents' perceptions of the functional relevance of mother language instruction and communication in various sociocultural contexts. Data were gathered from a representative sample with a self-structured questionnaire, and the responses were analysed statistically. The findings indicate a robust and favourable perception of mother-tongue education in improving understanding and engagement in the classroom. The study indicates that indigenous languages are essential for cultural preservation and function as effective instruments for promoting equity, trust, and inclusive national development. The study advised that reconciliation and trauma recovery initiatives should emphasise the use of local languages to enhance trust, engagement, and emotional healing, particularly in regions impacted by violence.
