Antonyms for "breaking the news" are keeping quiet, withholding information, and concealing the truth. Keeping quiet suggests that one refrains from announcing information, while withholding information means not disclosing it. Concealing the truth implies that someone intentionally hides or masks the reality. All of these antonyms share the common theme of not revealing something. They can arise from fear, deceit, or the decision that the information should not be shared. They are often used in professional, personal, or social settings where discretion and privacy are paramount, so not breaking the news may mean preserving someone's privacy or avoiding causing distress to others.
