Proto-Sino-Tibetan

Reconstruction

  • Proto-Sino-Tibetan: *ljum (Coblin, 1986)
    • Proto-Tibeto-Burman:
      • *lum (Benedict, 1972)
      • *s-lum ⪤ *lim (Matisoff, 2003)
      • *s-l(u/i)m (STEDT)

Chinese  / 𬊈 (to warm up) is usually cited as  / in Sino-Tibetan etymological literature. Schuessler (2007), Hill (2019), Baxter & Sagart, and STEDT all do this. In fact, Baxter & Sagart's reconstruction of *sə-l[ə]m is nominally assigned to  / . However, actual attestations of  / with the meaning of  / 𬊈 have not been substantiated.

Verb

*lum

  1. to be warm
