Explanation:

The term Bodo finds its first mention in the book by Hodgson in 1847, as a term of self-designation of the Mech and Kachari peoples. Grierson took this term Bodo to denote a section of the Assam-Burma group of the Tibeto-Burman languages of the Sino-Tibetan family, which included the languages of (1) Mech; (2) Rabha; (3) Lalung (Tiwa); (4) Dimasa (Hills Kachari); (5) Garo (6) Tiprasa and (7) Chutiya. In modern usage, the umbrella-term Bodo is more anthropological and linguistic in its usage. Modern historian Jae-Eun Shin use the Bodo as a linguistic group to include cognate groups. This umbrella-group includes such sub-groups as Mech in Bengal and Nepal; Boros, Dimasa, Chutia, Sonowal, Rabha, Tiwa in Assam, and the Kokborok people in Tripura and Bangladesh. This is in contrast to popular and socio-political usage, where Bodo denotes the politically dominant sub-group—the Boros—in the Bodoland Territorial Autonomous Districts.In general, the Boros or Bodo people means Boro people and scholars use the term Bodo to name the linguistic and anthropological group.
