Tibeto-Burman languages
The Tibeto-Burman languages are the non-Sinitic members of the Sino-Tibetan language family, over 400 of which are spoken throughout the Southeast Asian Massif ("Zomia") as well as parts of East Asia and South Asia. Around 60 million people speak Tibeto-Burman languages. The name derives from the most widely spoken of these languages, Burmese and the Tibetic languages, which also have extensive literary traditions, dating from the 12th and 7th centuries respectively. Most of the other languages are spoken by much smaller communities, and many of them have not been described in detail. Though the division of Sino-Tibetan into Sinitic and Tibeto-Burman branches (e.g. Benedict, Matisoff) is widely used, some historical linguists criticize this classification, as the non-Sinitic Sino-Tibetan languages lack any shared innovations in phonology or morphology to show that they comprise a clade of the phylogenetic tree. History During the 18th century, several scholars noticed parallels between Tibetan and Burmese, both languages with extensive literary traditions. In the following century, Brian Houghton Hodgson collected a wealth of data on the non-literary languages of the Himalayas and northeast India, noting that many of these were related to Tibetan and Burmese. Others identified related languages in the highlands of Southeast Asia
