Comment: Cf. also Ag. Bursh. aʕ-za- 'to stand', Tsakh. o=zar- 'to become tired' (for the semantics cf. Russ. 'стоять' - 'уставать'). In Tab. there exist two synonymous variants: ʁ-uz-uz (Düb. uʒ-us) and ʁ-ud-už̌-uz (Düb. q:-uǯ̌-us) 'stand up', reflecting probably proto-Tabasaran variants *ʔoc:V- (with secondary delabialisation) and *ʔec:ʷV- (preserving the labialisation). Note the common prefixation (*q:-) in Lezg., Tab., Ag., Kryz. and Bud.
