Proto-Lezghian: *q̇ärVq̇ʷ / *q̇ärVqʷ
Meaning: 1 sheepskin 2 sheepskin coat 3 coat of mail 4 shell
Lezghian: q̇erq̇ 1,3
Tsakhur: q̇arq̇ʷ 2
Budukh: q̇erq 4
Comment: 4th class in Tsakh. and Bud. In Lezg. the root means simultaneously "a piece of sheepskin" and "coat of mail". The disyllabic structure must be reconstructed to account for the preservation of -r- in Tsakh. (the cluster *-rq̇ʷ- would have yielded -q̇ʷ-); another solution would be to reconstruct *-lq̇ʷ, but this is against the external evidence.
