This Proto-Sino-Tibetan entry contains reconstructed words and roots. As such, the term(s) in this entry are not directly attested, but are hypothesized to have existed based on comparative evidence.



  • Proto-Sino-Tibetan: *ʔjit (Coblin, 1986)
    • Proto-Tibeto-Burman: *ʔit (Matisoff, STEDT); *it (Benedict, 1972)

There is no single general root for ONE in Sino-Tibetan languages, in sharp contradistinction to the cases of numerals 2-9, for each of which a single etymon overwhelmingly predominates. This root is only found at the periphery of the Sino-Tibetan area and may therefore be quite old. The more common root for ONE is *tjak ~ g-t(j)ik.

Benedict (1972) set up this etymon on the basis of only two forms: Kanawari and Written Burmese, and identified it as cognate to Old Chinese.

Matisoff (1997) posits *-i- ~ -ya- variational pattern in this etymon (akin to *tjak ~ g-t(j)ik (one), *gip ~ gjap (ten) and perhaps *riŋ ~ rjaŋ (ten), op. cit.) and considers this root to be etymologically cognate with *kat (one).

Some Min Dong dialects of Chinese use as the colloquial word for the numeral one, e.g. Fuzhou /soʔ⁵/, Fuqing /θyo⁵³/. Min Nan also has a similar-shaped word, e.g. Amoy /t͡ɕit̚⁵/.
