Deori language
Deori is a Tibeto-Burman language in the Sino-Tibetan language family spoken by the Deori people of Assam and Arunachal Pradesh. Only one clan of the Deori tribe, the Dibongya, has retained the language, the others having shifted to Assamese, but among the Dibongya it is vigorous..
Deori is spoken in Lohit district, Arunachal Pradesh, and in Lakhimpur district, Dhemaji district, Tinsukia district, and Jorhat district of Assam.
The Deori word for water is "Di/Dji", which apparently forms the first syllable of all major rivers of Upper Assam including Dibang, Disang, Dikhou, Dikrong, Dikarai, Dihing, Digaru, Difolu, which shows that this group of people were the dominant tribe in the entire region with their seat in Sadiya, the earliest known power and civilisation of Deori
