Proto-Lezghian: *ʔaq̇:Iʷä
Meaning: to lock, fasten
Tabasaran: qI-a=q:I- (Düb)
Rutul: s-a=q:e-
Archi: d-aq̇:Ia-
Comment: Cf. Arch. dur. darq̇:Iur. Unclear is the loss of pharyngealisation in Rut. (cf. also l-a=q:e- 'to unlock'). Besides the forms mentioned above, we must note a strange development in lit. Tabasaran and the Southern dialect: qI-a=q̇I- (with irregular -q̇I-, opposed to regular -q:I- in Northern Tab.). This could be a separate root, connected with Arch. erq̇Iʷin- 'to conceal, put away' - however, the Archi form itself may be related to d-aq̇:Ia-s (in most forms -q̇Iʷ- here occurs in a syllable-final position - like inf. erq̇Iʷmus etc. - and it may in fact represent the morphonemic *q̇:Iʷ).
