'mistakenly-verified' originates from the combination of 'mistakenly' and 'verified'. 'Mistakenly' comes from 'mistake', which originates from Old Norse 'mistaka', meaning 'to take in error'. 'Verified' comes from Latin 'verificare', where 'verus' meant 'true' and 'facere' meant 'to make'.

'Mistakenly' evolved from Middle English 'mistaken', and 'verified' from Middle English 'verifien', eventually forming the modern English compound 'mistakenly-verified'.

Initially, 'mistakenly' meant 'in error', and 'verified' meant 'confirmed as true'. Together, they evolved to mean 'incorrectly confirmed'.
