'wrongly-changed' originates from the combination of 'wrongly,' meaning 'in an incorrect manner,' and 'changed,' the past participle of 'change,' meaning 'to make or become different.'

'wrongly' and 'changed' have been used in English since the Middle Ages, with 'wrongly' deriving from Old English 'wranglice' and 'changed' from Old French 'changier.'

Initially, 'wrongly' meant 'in a wrong manner,' and 'changed' meant 'to alter.' The combination retains these meanings in modern usage.
