There are two dozen languages of Bhutan, all members of the Tibeto-Burman language family except for Nepali, which is an Indo-Aryan language, and Bhutanese Sign Language. Dzongkha, the national language, is the only language with a native literary tradition in Bhutan, though Lepcha and Nepali are literary languages in other countries. Other non-Bhutanese minority languages are also spoken along Bhutan’s borders and among the primarily Nepali-speaking Lhotshampa community in South and East Bhutan.
