Regurgitate comes from Medieval Latin regurgitatus, past participle of regurgitare ('to overflow'), from re- ('back') + Latin gurges ('whirlpool, gulf'). The historical chain includes Latin re-, Latin regurgitare, and Latin gurges. Older glosses in the chain include "to overflow", "back", and "whirlpool, gulf", which help explain the semantic range of the modern word. Morphologically, regurgitate is best read as compound and borrowing, yielding an English verb shaped by both form history and later usage. In current English it functions as a verb, with the sense "to bring swallowed food back up; to repeat information uncritically". English derivatives include regurgitation, regurgitated, regurgitating, and regurgitant; related forms include gurgle. The result is an English verb whose etymology preserves the older forms while supporting the word's specialized modern meaning.
