atestigüen

Atestigüen is a conjugated form of the Spanish verb atestiguar, meaning to attest, verify, or bear witness to something. It is the present subjunctive form for the third-person plural and for the ustedes form (ellos, ellas, ustedes). In practice, it appears in subordinate clauses requiring the present subjunctive and can also serve as the command form addressed to multiple people in formal or directive contexts, where the subjunctive mood is used to express a directive or expectation.

Etymology and morphology: The verb atestiguar derives from the sense of witness or testimony, linked to the noun testigo and related verbs such as testificar. The form atestigüen preserves the typical -ar verb pattern in the present subjunctive, with the diaeresis over the u to indicate the correct pronunciation of the gue sequence.

Usage: Atestigüen is used in sentences that express doubt, possibility, necessity, desire, or emotion, and in clauses that require the subjunctive mood. It also appears in formal commands directed at multiple people, since commands with ustedes employ the subjunctive form.

Examples:

- Es posible que atestigüen la autenticidad de los documentos.

- Exigieron que atestigüen los hechos ante la comisión.
