forbid

This word carries a strong sense of authority and official mandate. It is typically used when a person in power, a legal entity, or a strict set of rules imposes a prohibition. While it can be used in casual settings, it often implies a formal or absolute restriction rather than a mere suggestion to avoid something. When used to describe circumstances, such as weather or physical barriers, the word shifts from an act of will to an act of prevention. In these cases, it describes an external force that renders an action impossible, creating a barrier that cannot be overcome.
