Giving permission is the act of allowing or granting someone authority to do something. The antonyms of giving permission, on the other hand, refer to restricting, forbidding, or preventing someone from acting a certain way. These antonyms include denying, refusing, withholding, banning, prohibiting, and disallowing. When a person is denied permission, they are not allowed to proceed with their intended action. Refusing permission means the person is actively choosing not to grant authorization. Withholding permission is delaying the granting of permission until certain conditions are met, while banning prevents someone from doing something altogether. Prohibiting and disallowing both refer to forbidding someone from acting a certain way.
