Sino-Tibetan, also cited as Trans-Himalayan in a few sources, is a family of more than 400 languages, second only to Indo-European in number of native speakers. The vast majority of these are the 1.3 billion native speakers of Chinese languages. Other Sino-Tibetan languages with large numbers of speakers include Burmese and the Tibetic languages. Other languages of the family are spoken in the Himalayas, the Southeast Asian Massif, and the eastern edge of the Tibetan Plateau. Most of these have small speech communities in remote mountain areas, and as such are poorly documented.
The Tibetic languages form a well-defined group of languages descended from Old Tibetan. According to Tournadre (2014), there are 50 languages, which split into over 200 dialects or could be group into 8 dialect continua. These languages are spoken in the Tibetan Plateau and in the Himalayas in Gilgit-Baltistan, Aksai Chin, Ladakh, Nepal, Himachal Pradesh, Uttarakhand, and Bhutan. Classical Tibetan is the major literary language, particularly for its use in Buddhist literature.
Tshangla is a Sino-Tibetan language of the Bodish branch closely related to the Tibetic languages.

Tshangla is the principal pre-Tibetan language of Bhutan.

The Tibeto-Kanauri languages, also called Bodic, Bodish–Himalayish, and Western Tibeto-Burman, are a proposed intermediate level of classification of the Sino-Tibetan languages, centered on the Tibetic languages and the Kinnauri dialect cluster. The conception of the relationship, or if it is even a valid group, varies between researchers.
