'rejuvenate' originates from Latin, specifically the word 'rejuvenare,' where 're-' meant 'again' and 'juvenis' meant 'young.'

'rejuvenare' transformed into the French word 'réjuvénér,' and eventually became the modern English word 'rejuvenate' through Middle English.

Initially, it meant 'to make young again,' and over time it evolved into its current meaning of 'to restore to a youthful state.'
