Proto-North Caucasian: *HVrχ_E
Meaning: shed, stall
Notes: Although not very widely spread (which is the reason for uncertainty in vocalic reconstruction), the etymology seems phonetically and semantically quite plausible. The medial resonant -r- is reconstructed because of the correspondence PA *-χ:- : PTs *ʁ: (without the resonant we would expect *-χ- in PA); unfortunately, languages which could have preserved the -r-, have not preserved the root.
