'misannounce' originates from the prefix 'mis-' meaning 'wrongly' and the verb 'announce' from Latin 'annuntiare', where 'ad-' meant 'to' and 'nuntiare' meant 'report'.

'misannounce' evolved from the combination of 'mis-' and 'announce', which itself came from the Latin 'annuntiare'.

Initially, it meant 'to report wrongly', and this meaning has largely remained the same in modern usage.
