disallowed

Disallowed is an adjective meaning not allowed; forbidden by rules, laws, or policies. It describes conduct or items that authorities prohibit or restrict. The term is commonly used in formal or regulatory contexts and contrasts with allowed or permitted.

In law and governance, activities may be declared disallowed by statute, regulation, or license terms, with penalties for non-compliance. In procedural documents, disallowed actions are those that fail to meet requirements or violate conditions, making them invalid or ineligible.

In digital platforms, disallowed content or behavior violates terms of service or community guidelines and can trigger removal, warnings, or account suspension. In sports, disallowed moves or fouls are prohibited by the rulebook. In workplaces, disallowed practices may be unsafe or unethical, subject to discipline.

Disallowed is related to prohibited or forbidden; disallow is the verb form. In policy writing, choosing disallowed provides a formal tone; it is commonly interchangeable with prohibited, though some contexts prefer a stronger term. The concept exists to guide behavior and establish consequences.
