'honestly' originates from Old French, specifically the word 'honesté,' where 'honest' meant 'honorable.' 'Announce' originates from Latin, specifically the word 'annuntiare,' where 'ad-' meant 'to' and 'nuntiare' meant 'to report.'

'honesté' transformed into the Middle English word 'honeste,' and eventually became the modern English word 'honest.' 'Annuntiare' transformed into the Old French word 'anoncer,' and eventually became the modern English word 'announce.'

Initially, 'honest' meant 'honorable,' but over time it evolved into its current meaning of 'truthful.' 'Announce' initially meant 'to report,' and this meaning has largely remained the same in modern usage.
