atestigües

Atestigües is the second-person singular present subjunctive form of the Spanish verb atestiguar. The verb means to attest, to bear witness to something, or to certify the truth of a claim. The present subjunctive form is used in subordinate clauses that express doubt, desire, necessity, emotion, or uncertainty, often after verbs or expressions that trigger the subjunctive.

In usage, atestigües appears in sentences such as: Es necesario que atestigües la veracidad de ese documento. Quiero que atestigües si la firma es auténtica. These constructions typically occur in formal or juridical registers, as well as in investigative or journalistic writing, where testimony or verification is required. The form is one of several subjunctive conjugations of atestiguar, which also include atestigüe (yo), atestigues (tú), atestiguemos (nosotros), atestigüen (ellos).

The word atestigües belongs to a family of terms related to testimony and verification. The verb atestiguar is used to indicate providing evidence or testimony, while its noun forms such as atestiguación or atestiguamiento refer to the act or process of attesting. The spelling with the diaeresis over the u (ü) signals the correct pronunciation and preserves the phonetic sequence before the following e, a feature common to some present-subjunctive forms ending in -gües.

Etymology traces atestiguar to roots connected with testimony and witness, linking to related Latin-derived terms like testimonio and testis.
