'unexpectedly-damaged' originates from the combination of 'unexpectedly' and 'damaged'. 'Unexpectedly' comes from 'unexpected', which is derived from Latin 'ex-' meaning 'out of' and 'spectare' meaning 'to look'. 'Damaged' comes from Old French 'damager', which means 'to cause loss or harm'.

'unexpectedly-damaged' combines the adverb 'unexpectedly' with the adjective 'damaged' to form a compound adjective.

Initially, 'unexpectedly' meant 'not expected', and 'damaged' meant 'harmed'. Together, they describe something harmed in an unforeseen manner.
