'carefully-examined' originates from the combination of 'carefully' and 'examined', where 'carefully' comes from 'care' meaning 'attention' and 'examined' from Latin 'examinare' meaning 'to weigh or consider'.

'carefully' evolved from Old English 'caru' meaning 'sorrow, anxiety' and 'examined' from Latin 'examinare', which transformed into the French 'examiner', eventually becoming the modern English 'examine'.

Initially, 'carefully' meant 'with care or concern', and 'examined' meant 'to weigh or consider'. Over time, 'carefully-examined' evolved to mean 'thoroughly inspected'.
