Tibetan

The Tibetic languages (Tibetan: བོད་སྐད།) are a cluster of Sino-Tibetan languages spoken primarily by Tibetan peoples, who live across a wide area of eastern Central Asia bordering the Indian subcontinent, including the Tibetan Plateau and the northern Indian subcontinent in Baltistan, Ladakh, Nepal, Sikkim, and Bhutan. Classical Tibetan is a major regional literary language, particularly for its use in Buddhist literature. (Wikipedia)
