'unforeseenly-directed' originates from the combination of 'unforeseenly' and 'directed'. 'Unforeseenly' comes from 'unforeseen', which is derived from 'un-' meaning 'not' and 'foreseen', the past participle of 'foresee', meaning 'to see beforehand'. 'Directed' comes from 'direct', which originates from Latin 'directus', meaning 'straight' or 'guided'.

'Unforeseenly' evolved from Middle English 'unforseen', while 'directed' evolved from Middle English 'directen', which was influenced by Old French 'directer'.

Initially, 'unforeseenly' meant 'not seen beforehand', and 'directed' meant 'guided'. Together, they convey the idea of being guided in an unexpected manner.
