'foreseeably-concealed' originates from the combination of 'foreseeably' and 'concealed'. 'Foreseeably' comes from 'foresee', which originates from Old English 'foreseon', meaning 'to see beforehand'. 'Concealed' comes from Latin 'concelare', where 'con-' meant 'together' and 'celare' meant 'to hide'.

'Foreseeably' evolved from the Old English 'foreseon' and 'concealed' from Latin 'concelare', eventually forming the modern English compound adjective 'foreseeably-concealed'.

Initially, 'foreseeably' meant 'in a manner that can be predicted', and 'concealed' meant 'hidden'. The compound adjective retains these meanings, indicating something hidden in a predictable manner.
