Proto-North Caucasian: *mhălV- ~ *mhănV-
Meaning: warm
Notes: Reconstructed for the PEC level. The Nakh, Darg. and Tab. forms are hard to separate, although we have to assume different as-/dissimilations to unite them (in PD obviously *wana- < *mana-, because genuine w- is very rare in PD; and either PN *mɦal- through dissimilation < *mɦan-, or PD, PL *manV- through assimilation < *malV-). Since interaction of this kind between two neighbouring resonants is very frequent in Caucasian languages, we think that the etymology is rather probable.
