What does divulger mean?
A divulger is a person who reveals information that was intended to remain private, secret, or confidential. The noun is the agent form of the verb 'divulge,' which means to make known what had been hidden. Because English speakers usually prefer shorter or more familiar alternatives — 'leaker,' 'informant,' 'source,' or simply 'someone who let slip' — 'divulger' has a distinctly formal, even literary flavor, appearing most often in legal, journalistic, and historical writing. Its connotations are neutral: whether the divulger is admired as a whistleblower exposing wrongdoing or blamed as a gossip betraying a confidence depends entirely on context and the nature of the secret disclosed. The word derives from the Latin 'divulgare,' meaning to publish or spread among the people, from 'di-,' broadly, plus 'vulgus,' the common crowd — so at root, to divulge is to make something known to everyone rather than keep it among the few.

Etymology of divulger
'Divulger' comes from the verb 'divulge,' borrowed into English from Latin 'divulgare' (to publish, make public), formed from 'di-' plus 'vulgus,' meaning the common people or the general public. The verb entered English in the late Middle Ages via Old French 'divulguer,' and the agent-noun form 'divulger' arose within English by adding the '-er' suffix. Cognate forms include 'divulgation' and 'divulgence,' and the same Latin root also gives us 'vulgar' and 'vulgarize.'
How divulger is actually used
'Divulger' is a formal, somewhat rare agent noun formed from 'divulge'; in everyday speech people more often say 'the person who leaked it' or use 'source' or 'informant.' It carries no strong connotation on its own — praise or blame depends on what is revealed and why.
