Reconstruction:Proto-Sino-Tibetan/b-ras

• Proto-Sino-Tibetan: ?
  • Proto-Tibeto-Burman: *b-ras (Matisoff, STEDT)

A connection between this root and Proto-Austronesian *bəʀas (“husked rice”) has been proposed (Sagart, 2002; Matisoff, STEDT), compare for instance Amis felac, Malay beras, Tagalog bigas, Malagasy vary, Chamorro pugas and Kelabit bera. Moreover, Burushaski bras (“rice”) may be a borrowed from a Sino-Tibetan language. Ferlus (2010) proposes an Austroasiatic origin & reconstructs putative root *C.rac, a nominal derivation from the verb *rac "to pull, to tear off, to reap". Still, Sagart (2011) deems Ferlus' supporting evidence for the reconstruction to be "flimsy". Also compare Sanskrit व्रीहि (vrīhi) and Proto-Dravidian *wariñci which might have come from the same Austroasiatic source or cognates.

The most probable Chinese comparanda are 糲 (OC *m·raːds, *m·rads, *m·raːd, “grain of rice”) and 稗 (OC *breːs, “polished rice”). The second one is sometimes compared with Khmer បាយ (baay, “cooked rice; to eat”). Benedict (1975) also relates Tibetan འབྲས་བུ ('bras bu, “fruit”) with 飯 (OC *bonʔ, *bons, “millet, cooked rice”) on the basis of the double meaning of this root (“rice, fruit”), however it's possible that the latter shares a common source with Proto-Mon-Khmer *puuŋ (“cooked rice”). Chinese 米 (OC *miːʔ, “uncooked rice”) likely comes from Proto-Sino-Tibetan *ma-j ~ mej (“rice, paddy”).

According to Schuessler (2007), Mizo ṭai (“species of rice”) may be a cognate along with Mizo rah (“fruit”), although Sagart (2002) associates it with Tibetan ཁྲེ (khre, “millet”), which possibly comes from Proto-Sino-Tibetan *khrəj (“millet, rice”).
