Distribution of Deori-Chutiya Language inUpper Assam, as reported in the Language Survey of India 1903

Deori (alsoDeuri) is aTibeto-Burman language in theTibeto-Burman languages family spoken by theDeori people ofAssam andArunachal Pradesh.^[2] Deori are also a part ofBodo–Kachari people. Among the four territorial groups only the Dibongiya have retained the language. The others—Patorgoyan, Tengaponiya, and Borgoyan—haveshifted toAssamese. It is spoken inLohit district ofArunachal Pradesh, and inLakhimpur,Dhemaji,Tinsukia,Sivasagar andJorhat districts ofAssam. The primary literary body of Deori is known as "deori chucheba chengcha" (Deori sahitya sabha).

In thecolonial times this language became associated with theChutia people erroneously,^[3] and came to be known as the "Chutia language" in theLinguistic Survey of India.^[4] Modern scholarship do not associate the Deori language with the Chutia community.^[5]

The Deori language is one of the most influential languages which has helped develop theAssamese language in Upper Assam.^{[citation needed]}

However, the word for water has a similar form in many other languages of the Sal branch of Sino-Tibetan to which Deori belongs, so it is not conclusive evidence that Deori speakers were the first to occupy this area.^[6]
