'unexpectedly-positioned' originates from the combination of 'unexpectedly' and 'positioned'. 'Unexpectedly' comes from 'unexpected', which is derived from the Latin 'ex-' meaning 'out of' and 'spectare' meaning 'to look'. 'Positioned' comes from 'position', which is derived from the Latin 'positio', meaning 'a placing'.

'Unexpectedly' evolved from the Old French 'despecter', and 'positioned' evolved from the Latin 'positio'.

Initially, 'unexpectedly' meant 'not foreseen', and 'positioned' meant 'placed'. Together, they describe something placed in an unforeseen manner.
