'fashionably-furnished' originates from the combination of 'fashionably' and 'furnished'. 'Fashionably' comes from 'fashion', which originates from Latin 'factionem', meaning 'a making or doing'. 'Furnished' comes from Old French 'furnir', meaning 'to provide or supply'.

'Fashionably' evolved from Middle English 'facioun', while 'furnished' evolved from Old French 'furnir'.

Initially, 'fashionably' meant 'in a manner of making', and 'furnished' meant 'to provide'. Over time, they combined to describe a stylishly equipped space.
