Nubri is a Tibeto-Burman language spoken by about 2000 ethnically Tibetan people living in Nubri Valley in northern Central Nepal, upper Gorkhā District of Gandaki Province. Nubri has at least three dialects as typified by the Prok, Lho and Sama village varieties. Nubri is largely undocumented and undescribed, with the exception of a lexicon. Nubri is perhaps most closely related to neighbouring Tsum language and the Kyirong variety of Tibetan spoken just across the border in Tibet. It has also been claimed to be closely related to Gyalsumdo. Like these languages it is tonal and shares many Tibetic grammatical features, but is uniquely different in many ways.
