Language plays a dominant role in human existence. It is a means of communication and the medium of instruction in school.. It is also a means of preserving people’s culture, enhancement of peace and conflict resolution in the society. Language is also used for regional integration, means of public enlightenment, debate and addressing socio-economic problems in the media. Unfortunately, some factors hinder the use of language for peace, conflict resolution and national development. These factors are high illiteracy level in the country, lack of local or indigenous language, poor recognition of indigenous language as people’s culture and inadequate time in the media to address social problems using appropriate register that promote peace and national development. This paper therefore recommended the inclusion of indigenous national language in the school curriculum, implementation of mass education programme by the government through free education, the recognition of indigenous language as the most significant aspect of people’s culture and the creation of enough time in the media to address social problems using appropriate registers that enhance peace and development.
