COMMENT: Reconstructed for the PEC level. The root is well preserved in Lezg. languages and somewhat worse - elsewhere. In PA we would expect -č̣:-; this rare phoneme was probably weakened through dissimilation.
Cf. perhaps also WC data: PAT *q̇ʷač̣́a preserved in Abkh. a-ʒ-q̇ʷáč̣́a "(water) pool".
