PROTO: *č̣wErHV (/*rHEč̣wV)
MEANING: cold
COMMENT: A common NC adjectival and nominal stem. It is not quite clear whether r- in PL *ruč̣(a) ( = Gunz. rɔč̣u) should be treated as a former class prefix or as part of the root. The latter hypothesis seems preferable, because in Nakh languages the word has no class prefixes. See Abdokov 1983, 104 (Tsez. : WC).
