'imprecisely-determined' originates from the Latin word 'imprecisus,' where 'im-' meant 'not' and 'precisus' meant 'cut off or defined,' combined with 'determinare,' meaning 'to set bounds or limits.'

'imprecisely-determined' evolved from the Latin 'imprecisus determinare' to the modern English term, maintaining its core meaning of lacking clear boundaries.

Initially, it meant 'not clearly defined,' and this meaning has largely remained the same in modern usage.
