'unforeseenly-created' originates from the combination of 'unforeseen' and 'created'. 'Unforeseen' comes from the prefix 'un-' meaning 'not' and 'foreseen' from 'foresee', which means 'to see beforehand'. 'Created' comes from the Latin 'creare', meaning 'to make, bring forth'.

'Unforeseen' evolved from Middle English 'unforseen', and 'created' from Latin 'creatus'.

Initially, 'unforeseen' meant 'not seen beforehand', and 'created' meant 'brought into existence'. The combined term 'unforeseenly-created' retains these meanings.
