'curve' originates from Latin, specifically the word 'curvus,' where 'curvus' meant 'bent or crooked.'

'curvus' transformed into the Old French word 'courbe,' and eventually became the modern English word 'curve' through Middle English.

Initially, it meant 'bent or crooked,' but over time it evolved into its current meaning of 'a smoothly flowing, bending line or surface.'
