The act or instance of revealing or disclosing something that was previously kept secret.
From divulge + -ment (English suffix that creates nouns from verbs, indicating the result or act of doing something). This is a more English-feeling alternative to the Latin divulgation.
Divulgement is the Anglo-Saxon-feeling noun form (using the -ment suffix) while divulgation is the fancy Latin form—they mean the same thing, but divulgement feels more natural to modern English speakers' ears.
