'effectively-separated' originates from the combination of 'effectively' and 'separated'. 'Effectively' comes from Latin 'effectivus', meaning 'creative, effective', and 'separated' comes from Latin 'separatus', meaning 'to divide'.

'effectively' evolved from the Latin 'effectivus' through Old French 'effectif', and 'separated' evolved from Latin 'separatus' through Middle English 'separaten'.

Initially, 'effectively' meant 'capable of producing a desired effect', and 'separated' meant 'to divide'. Together, they convey the idea of being divided in a manner that achieves a desired outcome.
