válida

válida is the feminine form of the adjective válido in Spanish and Portuguese, used to indicate that something is valid, acceptable, effective, or legally binding. The masculine counterpart is válido, and the plural forms are válidos (masculine) and válidas (feminine). The word derives from Latin validus, meaning strong or powerful, via the Romance languages’ evolution of the root val-.

In everyday usage, válida describes entities that meet required conditions or are currently in effect. Examples include documentos válidos, billetes válidos, or firmas válidas in Spanish, and documentos válidos, boletos válidos, or assinatura válida in Portuguese. It is commonly found in legal, administrative, travel, and commerce contexts, where describing the validity of documents, permissions, licenses, or authorizations is important.

The related noun validez denotes validity or legal force, as in la validez de un contrato or a validez de una ley. The term is closely tied to concepts such as vigencia and eficacia, depending on the context. Accent marks on á in válidos and válidas indicate the stressed syllable in both languages.

Notes on usage: válida agrees in gender with the noun it modifies (una cédula válida, un permiso válido; uma cédula válida, uma licença válida). Although typically used in formal or semi-formal registers, it also appears in everyday language when affirming that something is legally or practically acceptable.
