'profuse' originates from Latin, specifically the word 'profusus,' where 'pro-' meant 'forth' and 'fundere' meant 'to pour.'

'profusus' transformed into the Old French word 'profus,' and eventually became the modern English word 'profuse' through Middle English.

Initially, it meant 'poured forth,' but over time it evolved into its current meaning of 'abundant or generous.'
