The Tibetic languages 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.
The Central Tibetan language (the dialects of Ü-Tsang, including Lhasa), Khams Tibetan, and Amdo Tibetan are generally considered to be dialects of a single language, especially since they all share the same literary language, while Dzongkha, Sikkimese, Sherpa, Ladakhi, and Balti are generally considered to be separate languages.
The Tibetic languages are spoken by some 8 million or more people. With the worldwide spread of Tibetan Buddhism, the Tibetan language has spread into the western world and can be found in many Buddhist publications and prayer materials, with some western students learning the language for translation of Tibetan texts. Outside of Lhasa itself, Lhasa Tibetan is spoken by approximately 200,000 exile speakers who have moved from modern-day Tibet to India 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.
Although some of the Qiang peoples of Kham are classified by China as ethnic Tibetans, Qiangic languages are not Tibetic, but rather form their own branch of the Sino-Tibetan language family.
Classical Tibetan was not a tonal language, but some varieties such as Central and Khams Tibetan have developed tone registers. Amdo and Ladakhi-Balti are without tone. Tibetic morphology can generally be described as agglutinative.
