'sequentially-verified' originates from the combination of 'sequentially' and 'verified'. 'Sequentially' comes from the Latin 'sequentia', meaning 'sequence', and 'verified' comes from the Latin 'verificare', meaning 'to make true'.

'Sequentially' evolved from the Latin 'sequentia' through Old French 'sequencial', and 'verified' evolved from the Latin 'verificare' through Old French 'verifier'.

Initially, 'sequentially' meant 'in a sequence', and 'verified' meant 'to make true'. Together, they evolved to mean 'confirmed in a step-by-step manner'.
