'imprecisely-measured' originates from the combination of 'imprecisely' and 'measured'. 'Imprecisely' comes from the Latin 'im-' meaning 'not' and 'precisus' meaning 'cut off, brief'. 'Measured' comes from the Latin 'mensurare', meaning 'to measure'.

'Imprecisely' evolved from the Latin 'imprecisus', and 'measured' from 'mensurare', eventually forming the modern English term 'imprecisely-measured'.

Initially, 'imprecisely' meant 'not precise', and 'measured' meant 'to ascertain the size or amount'. Together, they describe something not accurately quantified.
