Proto-North Caucasian: *ƛErV ( ~ -l-)
Meaning: river, rivulet
Proto-West Caucasian: *ʎ́a- Notes: An Av.-And.-Tsez.-WC isogloss. The etymology is possible, but not secure enough: the uncertainty is caused by problems of morphological analysis of Andian forms (unclear component -s:o(n)), Tsezian reduplication and the isolated character of the Shapsug form within WC (also with an etymologically unclear component -ħa).
