The essays in the volume explore how multilinguism operates in Manipur. They describe various aspects of languages spoken in Manipur to delve into the demographic, socio-cultural, religious, political, institutional, economical, historical and socio-psychological spheres of languages. They discuss the linguistic ecology in the state referring to different tribes and their languages including the Meitei, Koireng, Kom, Tarao, Aimol, Liangmai and Hmar. The book analyses what transforms language behaviour of people and views linguistic ecology and abilities as important factors in group categorisation, identification and maintenance in Manipur and the north-east Indian region as a whole.
