quatio

From Proto-Italic *kʷatjō.

Probably from Proto-Indo-European *(s)kwot-i- (“to shake; to thrive”) (possibly borrowed from a substrate), and cognate with Lithuanian kùsti (“to recover”), Old High German scutten (“to shake”), Old Norse hossa (“to throw”).^[1] Alternatively, from Proto-Indo-European *(s)kweh₁t- (“to shake”) (AHD), and cognate with Ancient Greek πάσσω (pássō), παστός (pastós).
