'dependably-furnished' originates from the combination of 'dependably' and 'furnished'. 'Dependably' comes from 'depend', which originates from Latin 'dependere', meaning 'to hang down'. 'Furnished' comes from 'furnish', which originates from Old French 'furnir', meaning 'to provide'.

'Dependably' evolved from the Latin 'dependere' through Old French 'dependre', and 'furnished' evolved from Old French 'furnir'.

Initially, 'dependably' meant 'in a manner that can be relied upon', and 'furnished' meant 'provided with furniture'. The combined term retains these meanings.
