The Dimasa language is a Tibeto-Burman language spoken by the Dimasa people of the Northeastern Indian states of Assam and Nagaland. The Dimasa language is known to Dimasas as "Grao-Dima" and it is similar to Boro, Kokborok and Garo languages.

Etymology

The Dimasa language is one of the oldest languages spoken in North East India, particularly in Assam, Nagaland. The word Dimasa etymologically translates to "Son(s) [sa] of the big river [dima]", i.e. the mighty Brahmaputra. The Dimasa word di, meaning water, forms the root of the names of many of the major rivers of Assam and of North East India in general, such as Dibang (plenty of water), Diyung (huge river), Dikrang (green river), Dikhow (fetched water), and many others. The Brahmaputra is known as Dilao (long river) among the Dimasas even now.

Many of the important towns and cities in Assam and Nagaland received their names from Dimasa words such as Diphu, Dimapur (a capital of the Dimasa Kingdom), Hojai, Khaspur, etc. In fact, the Dimasa language is one of the last languages of North East India to retain its original vocabulary without being compromised by foreign languages.^[2]
