'divulge' originates from Latin, specifically the word 'divulgare,' where 'di-' meant 'widely' and 'vulgare' meant 'to make known.'

'divulgare' transformed into the Old French word 'divulger,' and eventually became the modern English word 'divulge' through Middle English.

Initially, it meant 'to make widely known,' and this meaning has largely remained the same in modern usage.
