'unexpectedly-verified' originates from the combination of 'unexpectedly' and 'verified'. 'Unexpectedly' comes from 'unexpected', which is derived from the Latin 'ex-' meaning 'out of' and 'spectare' meaning 'to look'. 'Verified' comes from the Latin 'verificare', where 'verus' meant 'true' and 'facere' meant 'to make'.

'Unexpectedly' evolved from the Old French 'despecter', and 'verified' from the Old French 'verifier'.

Initially, 'unexpectedly' meant 'not foreseen', and 'verified' meant 'to make true'. Over time, the combination has come to mean 'confirmed in an unforeseen manner'.
