Which word means to denounce or condemn; to prohibit or forbid?

The term "proscribe" specifically means to denounce or condemn something, as well as to prohibit or forbid it. This word is often used in legal or formal contexts where certain actions, behaviors, or items are declared unacceptable and are thus banned or forbidden by authority.

Understanding "proscribe" in this way highlights its dual function: it not only communicates disapproval but also carries the weight of a prohibition, making it clear that the act is discouraged and officially not permitted. Therefore, this choice captures both the essence of condemnation and the notion of forbidding.

The other words have different, though somewhat related, meanings. "Condemn" focuses primarily on expressing strong disapproval, but it doesn’t necessarily imply prohibition. "Repudiate" carries a sense of rejection or disavowal but doesn't inherently include a prohibition aspect. "Dissuade" involves persuading someone not to do something but doesn't inherently express condemnation or prohibition.
