'voluptuous' originates from Latin, specifically the word 'voluptuosus,' where 'voluptas' meant 'pleasure.'

'voluptuosus' transformed into the Old French word 'voluptueux,' and eventually became the modern English word 'voluptuous.'

Initially, it meant 'full of pleasure or delight,' but over time it evolved into its current meaning of 'characterized by luxury or sensual pleasure.'
