The majority of these speakers, however, live in Nepal in their traditional homeland of Dolakhā District.
Thangmi is spoken in Bagmati Province, mainly in the region of Dolakha; villages on Sailung Khola (The northern panhandle of the Ramechhap District; mainly in Gokulganga); eastern regions of Sindhupalchowk District; and by some elders among the population who migrated to the cities in the Kathmandu Valley.
Studies from Konow (1909), Shafer (1966), Stein (1970), Toba (1990), van Driem (1992) and Turin demonstrate that Thangmi is closely related to the Rai and Newar languages.
Thangmi consists of two dialects, Dolakhā (East) and Sindhupālchok (West).
The Nepal Tham Society (NTS) produced a handful of Thangmi songs that were recorded in 2007.
