'luxury' originates from Latin, specifically the word 'luxuria,' where 'luxus' meant 'excess or extravagance.'

'luxuria' transformed into the Old French word 'luxurie,' and eventually became the modern English word 'luxury' through Middle English.

Initially, it meant 'excess or extravagance,' but over time it evolved into its current meaning of 'something adding to pleasure or comfort but not absolutely necessary.'
