Proto-North Caucasian: *rHaχwVnV ( ~ -ǝ-)
Meaning: mirror
Notes: A stem common for the Eastern area of Daghestan; it looks like a deverbative noun, but the producing stem is unknown. Phonetically correspondences are regular; the laryngeal in *rH- is suggested by PD pharyngealisation and by the development *r- > r- in PL (normally *r- > j-).
