Comment: All forms are in fact verbal adjectives. The verbal forms are widely preserved: Lezg. q̇ura-z (praet. q̇ura-na) 'to dry', Tab. u-r-q:u-z 'to get stale', Ag. ruq:ʷa-s (Bursh. urq:ʷa-s) 'to dry', Arch. q̇ura-s (imper. q̇uraq̇:a)/ q̇ʷa-s id. The Rut. and Bud. form may have been influenced by Turkic (cf. Azerb. Guru 'dry'), but there is no doubt in the authenticity of this root in PL.
