Language Lineage

Tibeto-Burman

Every Sino-Tibetan language except Chinese: some 450 languages, most of them small, with verb-final word order in almost all of them.

Into the Mountains

Tibeto-Burman is the traditional name for all the non-Chinese Sino-Tibetan languages. Only a few have a long written history (Tibetan, Burmese, Newar and Meitei), and hundreds are spoken by small communities in the valleys of the Himalayas, the hills of northeast India and Myanmar, and the mountains of southwest China. Almost all put the verb at the end of the clause, unlike Chinese and Karen. James Matisoff's Handbook of Proto-Tibeto-Burman (2003) reconstructs their common ancestor.

Whether Tibeto-Burman is a genuine branch, one that excludes Chinese, is disputed. The two 2019 phylogenies support it, but George van Driem argues that Chinese is just one branch among many and prefers the name 'Trans-Himalayan' for the whole family.

Agents, Agreement and Evidence

Beyond verb-final word order, Tibeto-Burman languages share a set of grammatical habits that set them apart from Chinese. Many mark the agent of a transitive verb with a special case ending (Written Tibetan -kyis/-gis, which also marks the instrument), but often only when the agent is unexpected, contrastive or needs emphasis. Randy LaPolla called this 'optional ergativity', and it is common across the Himalayas.

Verb agreement is the great puzzle. The Kiranti languages of eastern Nepal, such as Limbu and Bantawa, and rGyalrong in western Sichuan mark the person and number of both subject and object on the verb, with paradigms of dozens of forms. Other languages, Tibetan and Burmese among them, have no agreement at all. Scott DeLancey and George van Driem see the Kiranti and rGyalrong systems as inherited from Proto-Tibeto-Burman and lost elsewhere; LaPolla argues that they arose independently, later, in separate branches.

Many languages also build knowledge into grammar. In Lhasa Tibetan the choice between copulas such as yin and red ('is') depends on whether the speaker speaks from personal involvement or reports something as external fact, a system now usually called egophoricity. Similar distinctions between what the speaker saw, inferred or was told run through the languages of the plateau and the Himalayas.

    West and south into the mountains

    Tibeto-Burman speakers spread onto the Tibetan plateau, along the Himalayas and south into the hills of northeast India and Myanmar. Their subgroups diverge rapidly and in poorly understood order.

Contested classifications

These disagreements may never be settled. Each position is given with its grounds, and no side is declared correct.

  • Widely accepted

    Tibeto-Burman

    all non-Chinese Sino-Tibetan languages share an ancestor that Chinese does not

    Evidence for

    It is the traditional classification, used by Benedict and Matisoff, and both 2019 Bayesian phylogenies found Sinitic to be the first branch to split off, leaving the rest together.

    Evidence against

    Van Driem and others find no innovations shared by all the Tibeto-Burman languages alone, and argue that some of them may be closer to Chinese than to each other. On that view 'Tibeto-Burman' is simply 'Sino-Tibetan minus Chinese', and the family is better called 'Trans-Himalayan' with Chinese as one branch among many.
