atestigua

Atestigua is the third-person singular present indicative form of the Spanish verb atestiguar, meaning to attest, to bear witness to, or to certify a fact or document. In everyday use it can refer to verifying information, corroborating a statement, or confirming the authenticity of something, often in formal, legal, or administrative contexts.

Etymology and range of meaning: the verb atestiguar derives from earlier forms linked to testigo (witness) and testificar (to testify). The sense centers on providing confirmation or evidence that something is true or valid. Although related to testimony, atestiguar is not limited to legal settings and can appear in journalism, academia, and official communications when facts or sources are being verified.

Usage and forms: atestigua denotes the action performed by a subject in the present tense. Other common forms include atestiguó (pretérito perfecto simple), atestigüe (present subjunctive), and atestiguamos (nosotros). The verb is typically used with direct objects such as a hecho, documento, firma, o veracidad, for example: “El notario atestigua la firma,” “El informe atestigua la veracidad de los datos,” or “El perito atestiguó la autenticidad del documento.”

See also: testificar, certificar, verificar. Atestiguar is widely used in Spanish-speaking jurisdictions to indicate formal verification or witnessed corroboration of information or documents.
