Proto-North Caucasian: *ɦaʒ_ārV
Meaning: enclosure, wattle-fence
Notes: A Nakh-Lezg. isogloss. In PN the 1st syllable was reduced, and the laryngeal transferred into Inlaut, which conditioned a non-trivial development of *ʒ in the cluster. Nevertheless, the etymology seems rather probable.
A similar form exists in Tsez. (mecra 'enclosure for milking sheep'), but the nature of the initial m- here is quite obscure (the rest corresponds well to the PL form).
