'unexpectedly-guided' originates from the combination of 'unexpectedly' and 'guided'. 'Unexpectedly' comes from 'unexpected', which is derived from Latin 'ex-' meaning 'out of' and 'pectare' meaning 'to look'. 'Guided' comes from Old French 'guider', meaning 'to lead'.

'unexpectedly-guided' combines the adverb 'unexpectedly' with the past participle 'guided', forming a compound adjective.

Initially, 'unexpectedly' meant 'not expected', and 'guided' meant 'led or directed'. Together, they convey the idea of being led in an unforeseen manner.
