Proto-Sino-Tibetan: *Qʷɨj
Meaning: door, gate
Tibetan: sgo door, go place, room.
Comments: The Tib. form can be alternatively compared with OCh. 畿 *g_ǝj threshhold or 垓 *kǝ̄ territory; a comparison with OCh. 戶 *g_āʔ door (see Simon 13, Luce 2, Peiros-Starostin 217, Gong 47) is less probable, since the latter goes well together with PST *k(h)a open, opening.
