'foreseeably-progressing' originates from the combination of 'foreseeably' and 'progressing', where 'foreseeably' is derived from 'foresee', meaning 'to see beforehand', and 'progressing' from 'progress', meaning 'to move forward'.

'foreseeably' changed from the Old English word 'foreseon', and 'progressing' from the Latin word 'progressus', eventually becoming the modern English term 'foreseeably-progressing'.

Initially, 'foreseeably' meant 'able to be seen beforehand', and 'progressing' meant 'moving forward', but over time they combined to describe a state of expected advancement.
