    The comparison of PAT *qʷa- and PAK *q:ʷa- belongs to Abdokov (1973,55), and is certainly better than Klimov's (1967, 306) comparison of PAT *qʷa- with PAK *wǝ-xʷa- 'to bend' (absolutely impossible phonetically). Abdokov adds also Ub. q̇ʷarṭa- (sǝ-q̇ʷarṭá-n) 'to bend, be(come) crooked', but for phonetic reasons it seems better to choose Ub. q̇Iʷǝ- 'to bend' (thus following Shagirov 1,230). [Shagirov compares also Abkh. a-r-q̇ʷ-ra 'to bend (trans.), Abaz. čǝ-na-r-q̇ʷ-ra 'to bend', but this is a misunderstanding: the root here is PAT *q̇ʷǝ 'to lower, go down', and the meaning 'bend' is metaphorical (applied to fortune, circumstances and the like).]

    Besides PWC *q̇IʷV- the WC languages also reflect a phonetically close variant: *q̇́IʷV-, present in a compound *q̇́IʷV-rṭV / *q̇́IʷV-nṭV: Ub. q̇ʷarṭá- (see above), PAK *ʡʷanṭa- / *ʡʷarṭa- (Ad. ʡʷanṭa-, Shaps. ʡʷarṭa- 'to bend, crook', Kab. ʡʷanṭa- 'to twist').
