The word "prohibited" means "forbidden" or "not allowed." The word originates from the Latin term "prohibitio," which means "hindering." "Prohibited" is used as either the past tense of the verb "prohibit" or as an adjective describing something that is forbidden.
The noun form of the verb is "prohibition." Authorities declare prohibitions on many items and activities. For instance, some cities have a prohibition against loud radios in cars. Probably the most well-known use of the word "prohibition" is from the 18th amendment to the Constitution, which prohibited the manufacture and use of alcoholic beverages. The period of time during which this amendment was enforced is known as "Prohibition."
