Historically, Bumthang and its speakers have had close contact with speakers of the Kurtöp, Nupbi and Kheng languages, nearby East Bodish languages of central and eastern Bhutan, to the extent that they may be considered part of a wider collection of "Bumthang languages."^[4][5][6]

Bumthang language is largely lexically similar with Kheng (98%), Nyen (75%–77%), and Kurtöp (70%–73%); but less so with Dzongkha (47%–52%) and Tshangla (40%–50%, also called "Sharchop").^[2] It is either closely related to or identical with the Tawang language of the Monpa people of Tawang in India and China.^[2]

Bumthang is an ergative–absolutive language. The ergative case is not used on every transitive subject, but, like in so many other languages of the region shows some optionality, discussed in detail by Donohue & Donohue (2016).^[7]
