Abrogative is an adjective that refers to the act of repealing or abolishing a law, agreement, or custom. Some antonyms for this word include "confirming," "upholding," "preserving," and "maintaining." These antonyms signify the opposite of the abrogative action, suggesting that a law, agreement, or custom is being supported rather than abolished. For instance, if a law is confirmed, it is being upheld as valid and binding. Similarly, if an agreement is preserved, it is being maintained to ensure its continued existence. Therefore, the antonyms for abrogative highlight actions that reinforce and strengthen rather than weaken or eliminate.
