'unexpectedly-raised' originates from the combination of 'unexpectedly' and 'raised', where 'unexpectedly' comes from 'unexpected', meaning 'not anticipated', and 'raised' from 'raise', meaning 'to lift or elevate'.

'unexpectedly' evolved from the Old English 'un-' meaning 'not' and 'expect' from Latin 'expectare', while 'raised' comes from the Old Norse 'reisa'.

Initially, 'unexpectedly' meant 'not foreseen', and 'raised' meant 'lifted'. Together, they convey a sudden increase or elevation.
