This Dictionary of Mikir Language is in two parts:- Part-I is Mikir-English and Part-II is English-Mikir. This deals with the language of the Mikirs who are numerically the largest among the Assam Frontier races. They are scattered over a wide area from Golaghat to kamrup and the Khasi Hills beyond Guwahati and from Cachar plains to the north of Biswanath in Darrang District. The Mikir Language is of the Tibeto-Burmese groups. The present Dictionary was written about seven decades ago by a British Officer who served among the Mikirs and who showed extraordinary interest in mastering this language. The Dictionary will prove highly useful not only to the linguistic, eager to learn the intricacies of this language but also to all those who are posted to these remote frontier areas and who have to interact with their inhabitants.
