Proto-North Caucasian: *rVmƛ_Ă
Meaning: night, evening
Notes: It seems interesting to compare directly PN *(p)sa-lχEna and PWC *š́ʷǝ-Łʷa which may reflect one and the same compound *śwĔrV-rVmŁ_Ă. There are, however, some obscure points concerning both phonetic reconstruction and the semantic side here. The isogloss between Av. noƛ: and PD *duk:i is rather straightforward (although it does not allow to make a precise vocalic reconstruction); in WC and Nakh languages the root is used only in compounds, which of course obscures many phonetic details. [In fact, in PN there may have occurred a confusion of two EC roots: *rVmƛ_Ă 'night, evening' and *ƛăjV 'day, day-time' q.v.].
