'foreseeably-reduced' originates from the combination of 'foreseeably' and 'reduced'. 'Foreseeably' comes from 'foresee', which originates from Old English 'foreseon', meaning 'to see beforehand'. 'Reduced' comes from Latin 'reducere', meaning 'to bring back'.

'Foreseeably' evolved from the Old English 'foreseon', while 'reduced' evolved from the Latin 'reducere'. The combination of these words into 'foreseeably-reduced' is a modern English construct.

Initially, 'foresee' meant 'to see beforehand', and 'reduce' meant 'to bring back'. Over time, 'foreseeably-reduced' evolved to mean 'reduced in a predictable manner'.
