'regurgitation' originates from Latin, specifically the word 'regurgitatio,' where 're-' meant 'again' and 'gurgitare' meant 'to flood or engulf.'

'regurgitatio' transformed into the French word 'régurgitation,' and eventually became the modern English word 'regurgitation' through Middle English.

Initially, it meant 'to flood or overflow,' but over time it evolved into its current meaning of 'bringing swallowed food back up.'
