'imprecisely-managed' originates from the combination of 'imprecisely' and 'managed'. 'Imprecisely' comes from Latin 'im-' meaning 'not' and 'precisus' meaning 'cut off, brief'. 'Managed' comes from Italian 'maneggiare', meaning 'to handle'.

'Imprecisely' evolved from Latin 'imprecisus' through Old French 'imprecis', while 'managed' evolved from Italian 'maneggiare' through Middle French 'managier'.

Initially, 'imprecisely' meant 'not precise', and 'managed' meant 'handled'. Over time, 'imprecisely-managed' came to mean 'handled without precision'.
