wallow: [OE] To wallow is etymologically to ‘roll’ about. The word goes back ultimately to the Indo-European base *wol-, *wel- ‘roll’, which also produced English helix, involve, vault, volume, etc. From this was descended prehistoric Germanic *wal-, *wel- (source of English waltz, welter, etc, and possibly of wallet). The extended form *walw- produced West Germanic *walwōjan, which evolved into English wallow.
