Allowing is the act of giving permission, whereas dis-allowing means denying permission or forbidding something. Antonyms for dis-allowing, then, would be words that mean the opposite of forbidding. Some examples of antonyms for dis-allowing could be words like permitting, authorizing, approving, endorsing, or conceding. All of these words imply that someone or something is being given permission or permission is being granted. It is important to note that when using antonyms for dis-allowing, the context will also determine whether the word is appropriate. For instance, if someone says something is authorized, it means that it has been given permission to happen or exist, but it may still be subject to certain limitations or conditions.
