Proto-Lezghian: *ʔaq̇ʷVn
Meaning: 1 as much as 2 up to, until
Lezghian: aq̇ʷan 1
Tabasaran: -q̇an 1
Archi: eq̇en 2
Comment: The root is used as an adverb (Lezg. aq̇ʷan), postposition (Arch. eq̇en) or suffix (Tab. -q̇an, cf. also Lezg. -q̇ʷan with the same meaning and function). Historically this is obviously a gerundial form (cf. the same development in Andi).
