'exuberant' originates from Latin, specifically the word 'exuberare,' where 'ex-' meant 'out of' and 'uberare' meant 'to be fruitful.'

'exuberare' transformed into the French word 'exubérant,' and eventually became the modern English word 'exuberant' through Middle English.

Initially, it meant 'to be fruitful or abundant,' but over time it evolved into its current meaning of 'full of energy and cheerfulness.'
