'tidily-furnished' originates from the combination of 'tidily,' an adverb meaning 'in a neat and orderly manner,' and 'furnished,' the past participle of 'furnish,' meaning 'to provide with furniture.'

'Tidily' comes from the Old English word 'tidig,' meaning 'timely or seasonable,' and 'furnished' comes from the Old French 'furnir,' meaning 'to furnish or equip.'

Initially, 'tidily' meant 'timely,' but over time it evolved to mean 'neatly,' while 'furnished' has largely retained its original meaning of 'equipped with furniture.'
