proibido

Proibido is a Portuguese adjective meaning "forbidden" or "not allowed." It is used to indicate prohibition or restriction and agrees with the gender of the noun it modifies: proibido for masculine nouns and proibida for feminine nouns. As a predicative expression, it forms phrases such as "É proibido" ("It is forbidden"), while as an epithet it appears in compound terms like "área proibida" (restricted area).

The word derives from Latin prohibitus, the past participle of prohibere, meaning to prohibit. The root conveys the idea of keeping something away or preventing a given action.

In everyday use, proibido is common on road signs and public notices in Portuguese-speaking countries, for example "Proibido estacionar" (No parking), "Proibido fumar" (No smoking), and "Entrada proibida" (Entrance forbidden). In legal and regulatory language, constructions such as "é proibido" or "não é permitido" are standard.

In culture, proibido is a frequent stylistic element in titles and themes related to rules, transgression, or taboo, reflecting social norms and prohibitions. The word is part of a broader family that includes the verb proibir (to prohibit) and related forms used to describe what is not allowed.
