'sufficiently-furnished' originates from the combination of 'sufficiently' and 'furnished'. 'Sufficiently' comes from Latin 'sufficere', meaning 'to provide', and 'furnished' comes from Old French 'furnir', meaning 'to supply'.

'Sufficiently-furnished' combines the adverb 'sufficiently' and the past participle 'furnished', which evolved from the Old French 'furnir'.

Initially, 'furnished' meant 'to supply or provide', and 'sufficiently' meant 'adequately'. Together, they convey the idea of being adequately supplied.
