Confirmabais

Confirmabais is a conjugated form of the Spanish verb confirmar, which means "to confirm." It belongs to the regular -ar verb group and is used in the imperfect tense. In the imperfect indicative, confirmabais represents the second-person plural (vosotros/ustedes) and translates to "you all confirmed" or "you (plural) used to confirm." In Spain, the form vosotros is more common, whereas in most Latin American varieties, ustedes replaces vosotros, but the conjugation remains the same. For example: “Confirmabais que la fecha estaba correcta” (You all confirmed that the date was correct).

The same wording can appear in the imperfect subjunctive when referring to a hypothetical or uncertain action in the past, though it is less common. In literary or formal contexts, confirmabais may appear as a subjunctive form to express doubt or instruction: “Si confirmabais el plan, lo pondríamos en marcha.” Here it functions as a subjunctive, contrasting with the indicative confirmar + plural present subjunctive.

Confirmabais is not irregular; its stem remains confirmar for all simple forms: confirmaba (I confirmed), confirmabas (you singular), confirmaban (they), etc. The plural form beyond the second person is confirming that the verb behaves consistently with other -ar verbs such as trabajar and comer.

In summary, confirmabais is used historically for habitual or repeated confirmation actions in the past and occasionally in subjunctive constructions. It is a textbook example of the regular -ar verb conjugation pattern in Spanish.
