The Bumthang language (Dzongkha: བུམ་ཐང་ཁ་, Wylie: bum thang kha; also called Bhumtam, Bumtang(kha), Bumtanp, Bumthapkha, and Kebumtamp) is an East Bodish language spoken by about 20,000 people in Bumthang and surrounding districts of Bhutan.

[2][3] Van Driem (1993) describes Bumthang as the dominant language of central Bhutan.

"[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").

The telic suffix -QO, where both Q (realized as [k], [g], [ng], [t], or [d]) and O take on a different value based on the final consonant and vowel of a word, denotes the goal of a situation which the word is directed to (e.g. Thimphuk-gu 'to Thimphu', yam-do 'on the way').

TAM categories include the present, the experienced past, the inferred past, the experienced imperfective, the periphrastic perfect, the infinitival future, the volitional future, the supine, the gerund, the adhortative, and the optative.
