'expectedly-disproven' originates from the combination of 'expectedly' and 'disproven'. 'Expectedly' comes from 'expect', which originates from Latin 'expectare', meaning 'to look out for'. 'Disproven' is the past participle of 'disprove', which comes from Old French 'desprover', meaning 'to refute'.

'expectedly-disproven' combines the adverb 'expectedly' and the adjective 'disproven', forming a compound adjective in modern English.

Initially, 'expectedly' meant 'as anticipated', and 'disproven' meant 'shown to be false'. Together, they convey the idea of something anticipated to be false and confirmed as such.
