'carefully-aimed' originates from the combination of 'careful' and 'aimed', where 'careful' comes from Old English 'carful', meaning 'full of care', and 'aimed' from Old French 'esmer', meaning 'to estimate or intend'.

'careful' evolved from Old English 'carful', and 'aimed' from Old French 'esmer', eventually forming the modern English compound adjective 'carefully-aimed'.

Initially, 'careful' meant 'full of care', and 'aimed' meant 'to estimate or intend'. Over time, they combined to describe actions executed with precision.
