The Tibetic languages are a branch of the Tibeto-Burman languages in the Sino-Tibetan language family. Descending from Old Tibetan, there are 50 recognized Tibetic languages, which branch into more than 200 dialects, which could be grouped into eight dialect continua. These Tibetic languages are spoken in parts of China (Tibet, Aksai Chin), Pakistan (Gilgit-Baltistan), Nepal, Bhutan and India (Arunachal Pradesh, Assam, Uttarakhand, Himachal Pradesh, Sikkim). Classical Tibetan is the major literary language, particularly for its use in Tibetan Buddhist scriptures and literature.
Tibetan languages are spoken by some 6 million people, not all of whom are Tibetan. With the worldwide spread of Tibetan Buddhism, the Tibetan language has also spread into the western world and can be found in many Buddhist publications and prayer materials, while western students also learn the language for the translation of Tibetan texts. Outside of Lhasa itself, Lhasa Tibetan is spoken by approximately 200,000 exiled Tibetans who have moved from Tibet to India, Nepal and other countries. Tibetan is also spoken by groups of ethnic minorities in Tibet who have lived in close proximity to Tibetans for centuries, but nevertheless retain their own languages and cultures.
