Past tense of grovel: to crawl or act obsequiously, showing extreme submission or humiliation.
From grovel, possibly from Scandinavian 'gravlinga' or related to 'grove' (belly/prone position). It entered English around the 1600s to describe crawling on one's belly.
The word 'groveled' perfectly captures the physical reality of submission—you literally can't crawl on your belly while maintaining dignity, which is why the word became synonymous with humiliation.
