'precisely-aimed' originates from the combination of 'precisely' and 'aimed', where 'precisely' comes from Latin 'precisus', meaning 'cut off, brief', and 'aimed' from Old French 'esmer', meaning 'to estimate or intend'.

'Precisely' evolved from Latin 'precisus' through Old French 'precis', and 'aimed' from Old French 'esmer', eventually forming the modern English term 'precisely-aimed'.

Initially, 'precisely' meant 'cut off or brief', but over time it evolved to mean 'exactly or accurately', and 'aimed' retained its meaning of 'directed towards a target'.
