'wrongfully-returned' originates from the combination of 'wrongfully' and 'returned', where 'wrongfully' means 'in a manner that is not right or just' and 'returned' means 'sent back'.

'wrongfully' comes from Old English 'wrang' meaning 'wrong' and 'fully' from 'full', while 'returned' comes from Old French 'retourner', which means 'to turn back'.

Initially, 'wrongfully' meant 'in a wrong manner', and 'returned' meant 'sent back'. The combination retains the original meanings.
