Proto-North Caucasian: *rĕnƛ̣_wV̆ ( ~ -ä̆-)
Meaning: cloud, fog
Notes: Reconstructed for the PEC level. Correspondences between Av., PN and Khin. are regular; the PD form can belong here if we assume a partial reduplication (*ɣerɣʷa < *ɣereɣʷa). Some EC forms (Av., Nakh) are compared by Abdokov (1983, 99) with Abaz. tħʷa (probably taken from ps-tħʷa 'cloud'), which is phonetically impossible.
