The family of Chinese, Tibetan, Burmese and several hundred languages of the Himalayan and Southeast Asian uplands. Its two literary branches produced two of the largest religious canons ever assembled, and the internal structure of everything between them is still being worked out.

Facts
Disputed
Homeland Hypothesis
Either the upper Yellow River basin, tying the family to millet farming, or the eastern Himalayan foothills, where present diversity is greatest. 1
The two accounts rest on different kinds of evidence: archaeology and agricultural vocabulary on one side, the distribution of present-day diversity on the other. They imply different dates for the family and different directions of spread.
Classification Status
Accepted as a family, but its internal structure is among the least settled of any large family. Whether Chinese stands apart from everything else has been argued at length, and Tai-Kadai and Hmong-Mien, once included, are now usually excluded. 1
Thurgood and LaPolla's edited volume treats Sino-Tibetan's existence as a family as settled; what remains argued is its internal shape. One long-running question is whether Chinese forms its own primary branch standing apart from all the rest (a Sino-Tibetan split, sometimes called Sino-Bodic on the other reading) or whether it groups more closely with particular subfamilies within the rest of the family; specialists working from different subsets of shared vocabulary and sound-correspondence data have argued both positions since the family's classification was first proposed. A second, now largely settled question over the family's outer boundary illustrates how the internal debate proceeds: Tai-Kadai and Hmong-Mien were included in early twentieth-century classifications on the strength of shared vocabulary later shown to be the product of extensive contact and borrowing with Chinese rather than common descent, and both are now usually excluded on that reading. The Chinese-position question remains open because, unlike the Tai-Kadai and Hmong-Mien case, no comparable contact explanation has been demonstrated to account for the vocabulary linking Chinese to the rest of the family, leaving inheritance and an unusually deep split both still on the table.
Attestation
Earliest Attestation
Chinese, in the oracle bone inscriptions from about the thirteenth century BCE, by far the earliest record in the family. Tibetan is attested from the seventh century CE and Burmese from the twelfth. 1

One Family, Two Literatures and Four Hundred Languages

Sino-Tibetan holds the Chinese languages, Tibetan, Burmese and several hundred others spoken across the Himalayan foothills, the uplands of Southeast Asia and southwestern China. By speaker count it is second only to Indo-European, and almost all of that count sits in the Chinese branch. The rest of the family is extraordinarily diverse and comparatively little described: many of its languages have a few thousand speakers, no written tradition and no full grammar, and new ones are still being documented.

Relating them to each other is genuinely difficult. Chinese and Tibetan have both been written for well over a thousand years, but their early written forms are separated by so much time and so much borrowing that reconstruction has to work around loanwords in both directions, and the internal structure of the family is still an open field rather than a settled tree. Even the name has been argued over, since some scholars prefer Trans-Himalayan to avoid the implication that Chinese and Tibetan form a primary division. What is not in doubt is that the family exists, that Chinese and Tibeto-Burman are related, and that the connection was established through exactly the same comparative work that established Indo-European.

Two of the Largest Religious Canons Ever Assembled

Two branches of this family produced canons on a scale few traditions have matched. Classical Chinese carries the Confucian classics, the Daoist canon known as the Daozang, and the Chinese Buddhist Tripitaka, the last of which preserves translations of Indian works whose Sanskrit originals are lost. Classical Tibetan carries the Kangyur, the translated word of the Buddha, and the Tengyur, the translated commentaries, together running to more than three hundred volumes. Both were the product of deliberate state and monastic programmes: translation into Chinese ran for the better part of a millennium under successive dynasties, and the Tibetan effort involved the creation of a standardised technical vocabulary by imperial decree so that Sanskrit Buddhist terms would be rendered consistently across every workshop.

The consequence for anyone studying Buddhism is that the two largest surviving bodies of Buddhist literature are in two languages of a single family, neither of them the language any of it was composed in. The consequence for the family itself is that two of its members have written records deep enough to anchor the reconstruction of everything else, which is why the sparsely documented languages of the Himalayan foothills matter so much to specialists: they are where the undisturbed evidence is.
