Proto-North Caucasian: *=irG_wVr
Meaning: to freeze, get cold
Notes: Reconstructed for the PEC level. In PL and Cham. there occurred a secondary loss of labialization (before a front vowel?); otherwise the correspondences are regular (pharyngealization in PD is automatic, in the vicinity of a front vowel). A probable HU parallel is Hurr. e/igi, eg-o 'cold' (see Diakonoff-Starostin 1986, 60).
