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

'regurgitare' transformed into the French word 'regurgiter,' and eventually became the modern English word 'regurgitate' through Middle English.

Initially, it meant 'to flood or engulf again,' but over time it evolved into its current meanings of 'to bring swallowed food back up' and 'to repeat information without understanding.'
