Proto-North Caucasian: *jɦĕrq_wɨ̄ (~-ō)
Meaning: slope; ravine, ditch
Proto-West Caucasian: *q:ʷa Notes: The EC and WC forms match each other well, both phonetically and semantically. [Abdokov (1983, 95) compares the WC forms with Tab. q:Iar 'bridge' (a Southern dialectal form corresponding to lit. ʁIad) and Arch. qIar 'ravine' (cited as q:Iar) - a form we were unable to identify; this etymology certainly should be rejected.]
