When we talk about becoming ratified, we mean something has been approved or confirmed. An antonym for this could be "denied" or "rejected." If something is not ratified, it means it has not been recognized as valid or legal. Other antonyms for becoming ratified could include "disapproved," "opposed," "vetoed," or "nullified." These words represent an opposite meaning to the idea of being ratified, suggesting that something has been deemed invalid or unsuitable for approval. In short, the antonyms for "become ratified" are terms that represent the inability to acknowledge or confirm a certain action or decision.
