Tibeto-Burman languages
In the 1700s, researchers observed striking similarities between Tibetan and Burmese. Both languages possessed extensive literary traditions that spanned centuries. A model of dispersal for these languages later emerged to visualize their spread across Asia. During the following century, Brian Houghton Hodgson collected vast amounts of data on non-literary Himalayan tongues. He noted that many of these obscure dialects related closely to Tibetan and Burmese. Others identified similar languages in the highlands of Southeast Asia and south-west China. The name Tibeto-Burman first appeared in print in 1856 thanks to James Logan. He added Karen to this group two years later in 1858. Charles Forbes viewed the family as uniting the Gangetic and Lohitic branches of Max Müller's Turanian system. Julius Klaproth had noted in 1823 that Burmese, Tibetan and Chinese all shared common basic vocabulary. Ernst Kuhn described an Indo-Chinese family in 1883 with two distinct branches. August Conrady followed suit in 1896 with a similar description of an Indo-Chinese family. Jean Przyluski introduced the term sino-tibétain as the title of his chapter in 1924. Tai languages have not been included in most Western accounts since the Second World War.
Over 60 million people speak Tibeto-Burman languages across remote mountain areas today. These speakers inhabit the Southeast Asian Massif known as Zomia along with parts of East Asia and South Asia. The southernmost group consists of Karen languages spoken by three million people on both sides of the Burma, Thailand border. They differ from all other Tibeto-Burman languages except Bai in having subject-verb-object word order. This grammatical structure likely resulted from contact with Tai-Kadai and Austroasiatic languages. The most widely spoken language is Burmese with over 32 million speakers serving as the national language of Myanmar. A literary tradition for Burmese dates back to the early 12th century. It belongs to the Lolo-Burmese languages which comprise approximately 100 languages spoken in Myanmar and highlands of Thailand, Laos, Vietnam, and southwest China. Major languages include the Loloish languages with two million speakers in western Sichuan and northern Yunnan. The Akha language and Hani languages also feature two million speakers in southern Yunnan, eastern Myanmar, Laos and Vietnam. Lisu and Lahu appear in Yunnan, northern Myanmar and northern Thailand. All languages of the Loloish subgroup show significant Austroasiatic influence. The Pai-lang songs transcribed in Chinese characters during the 1st century record words from a Lolo-Burmese language arranged in Chinese order.
Some historical linguists criticize the division of Sino-Tibetan into Sinitic and Tibeto-Burman branches. They argue that non-Sinitic Sino-Tibetan languages lack shared innovations in phonology or morphology to prove they form a clade. Despite this criticism, the classification remains widely used by scholars like Benedict and Matisoff. Recent controversy has centred on the proposed primary branching of Sino-Tibetan into Chinese and Tibeto-Burman subgroups. In spite of its popularity, Tibeto-Burman has not been demonstrated to be a valid subgroup in its own right. Shafer's tentative classification took an agnostic position and did not recognize Tibeto-Burman as a distinct branch. He placed Chinese on the same level as other branches of a Sino-Tibetan family. Benedict envisaged Chinese as the first family to branch off followed by Karen. George van Driem rejects the primary split of Sinitic making Tibeto-Burman synonymous with Sino-Tibetan. Bradley incorporates much newer data published since 1972 regarding previously inadequately documented languages. Matisoff makes no claim that families in Kamarupan or Himalayish branches have a special relationship beyond geography. Randy LaPolla proposed a Rung branch based on morphological evidence but it is not widely accepted. Scott DeLancey proposed a Central branch of Tibeto-Burman based on morphological evidence in 2015.
The Tibeto-Burman family divides into seven primary branches according to Paul Benedict's influential work from 1972. These include Tibetan-Kanauri, Bahing-Vayu, Abor-Miri-Dafla, Kachin, Burmese-Lolo, Boro-Garo, and Kuki-Naga. Of the seven branches within Tibeto-Burman, two branches Baic and Karenic have subject-verb-object order. All other five branches maintain subject-object-verb order instead. James Matisoff proposes a modification of Benedict that demoted Karen but kept the divergent position of Sinitic. The internal structure includes Northeast Indian areal groups like Tani and Deng alongside Kuki-Chin and Naga areal groups. Sal contains Boro-Garo and Northern Naga/Konyakian languages while Jingpho-Asakian forms another cluster. Himalayish encompasses Western Himalayish Bodic Lepcha Tamangish Dhimal Newar Kiranti and Kham-Magar-Chepang. Tangut-Qiang covers Tangut Qiangic rGyalrongic Nungic Tujia Lolo-Burmese-Naxi Lolo-Burmese Naxi and Karenic Bai. Other unclassified languages include Basum Songlin Chamdo Koki Naga and several isolates recognized in the 2010s. Roger Blench and Mark Post list divergent languages of Arunachal Pradesh that might possess non-Tibeto-Burman substrates. These include Kamengic Bugun Mey Sartang Chug Lish Idu Taraon Siangic Koro Milang Puroik Hruso Miji and Miju.
Most Tibeto-Burman languages are spoken in remote mountain areas which has hampered their study significantly. Many lack a written standard making documentation extremely difficult for researchers. It is generally easier to identify a language as Tibeto-Burman than to determine its precise relationship with other languages. The subgroupings established with certainty number several dozen ranging from well-studied groups to isolates discovered recently. Some isolates were only found in the 21st century but face danger of extinction now. Over eight million people on the Tibetan Plateau speak related Tibetic languages with literature dating from the 8th century. Sizable groups identified include West Himalayish Tamangic Kiranti Newar Magaric Dura Raji-Raute Chepangic and Dhimalish. Lepcha spreads across an area from eastern Nepal to western Bhutan while most Bhutanese languages remain Bodish. Three small isolates exist there called Ole Lhokpu and Gongduk alongside Tshangla speakers. The Tani languages cover most of Arunachal Pradesh and adjacent Tibet areas. Remaining languages belong to Siangic Kho-Bwa Hruso Miju and Digaro groups with relatively little Tibeto-Burman vocabulary. Northern Myanmar hosts Nungish Jingpho-Luish Boro-Garo Konyak Ao Angami-Pochuri Tangkhulic Zeme Karbi Meithei and Kuki-Chin. The Mru language is spoken by a small group in Chittagong Hill Tracts between Bangladesh and Myanmar.
