'unexpectedly-directed' originates from the combination of 'unexpectedly' and 'directed'. 'Unexpectedly' comes from 'unexpected', which is derived from the Latin 'ex-' meaning 'out of' and 'pectare' meaning 'to look'. 'Directed' comes from the Latin 'directus', meaning 'straight' or 'guided'.

'unexpectedly' evolved from the Old French 'despecter', which transformed into the Middle English 'expecten', eventually becoming 'unexpected'. 'Directed' evolved from the Latin 'directus', through Old French 'directer', and into Middle English 'directen'.

Initially, 'unexpectedly' meant 'not looked for', and 'directed' meant 'guided'. Over time, 'unexpectedly-directed' came to mean 'guided in an unforeseen manner'.
