'luxuriously-furnished' originates from the word 'luxury,' which comes from the Latin word 'luxuria,' meaning 'excess' or 'extravagance.' The term 'furnished' is derived from the Old French 'furnir,' meaning 'to supply or provide.'

'luxuria' transformed into the Old French 'luxurie,' and eventually became the modern English word 'luxury.' 'Furnir' evolved into the Middle English 'furnish,' leading to the modern term 'furnished.'

Initially, 'luxuria' meant 'excess,' but over time it evolved into its current meaning of 'luxury,' denoting comfort and elegance.
