'carefully-decided' originates from the combination of 'carefully' and 'decided', where 'carefully' is derived from 'care' meaning 'attention' and 'decided' from 'decide' meaning 'to make a choice'.

'carefully' evolved from the Old English word 'caru' meaning 'sorrow, anxiety' and 'decided' from the Latin 'decidere' meaning 'to cut off'.

Initially, 'carefully' meant 'with care or concern', and 'decided' meant 'to make a choice'. Together, they evolved to mean 'made with careful consideration'.
