'imprecisely-verified' originates from the combination of 'imprecisely' and 'verified'. 'Imprecisely' comes from Latin 'im-' meaning 'not' and 'precisus' meaning 'cut off, brief'. 'Verified' comes from Latin 'verificare', where 'verus' meant 'true' and 'facere' meant 'to make'.

'Imprecisely' evolved from the Latin 'imprecisus' through Old French 'imprecis' and eventually became the modern English 'imprecisely'. 'Verified' transformed from the Latin 'verificare' through Old French 'verifier' and became the modern English 'verified'.

Initially, 'imprecisely' meant 'not exact or precise', and 'verified' meant 'to make true'. Together, they describe something confirmed without precision.
