'ingenious' originates from Latin, specifically the word 'ingeniosus,' where 'ingenium' meant 'natural capacity or talent.'

'ingeniosus' transformed into the Old French word 'ingenieux,' and eventually became the modern English word 'ingenious' through Middle English.

Initially, it meant 'having natural talent or cleverness,' but over time it evolved into its current meaning of 'cleverly and originally planned or created.'
