'imprecisely-depicted' originates from the combination of 'imprecisely' and 'depicted', where 'imprecisely' comes from Latin 'im-' meaning 'not' and 'precisus' meaning 'cut off, brief', and 'depicted' from Latin 'depictus', past participle of 'depingere', meaning 'to paint'.

'imprecisely' changed from the Latin 'imprecisus' to the modern English 'imprecisely', and 'depicted' evolved from the Latin 'depictus' to the modern English 'depict'.

Initially, 'imprecisely' meant 'not precise', and 'depicted' meant 'painted or represented', which has largely remained the same in modern usage.
