Common mistakes

  1. Wrong: Yo confirma la reserva del hotel. — Right: Yo confirmo la reserva del hotel. — The person matters: confirma is the él/ella/Ud. form, while the yo form is confirmo. Using the third-person form with yo is one of the most common beginner errors.
  2. Wrong: Treating confirmar and verificar as identical in every context. — Right: Confirmar means to confirm, while verificar means to verify something. — They overlap, but each has uses the other does not: confirmar fits sentences such as Confirmo la reserva del hotel, while verificar belongs in a different sentence. Check the meaning you want before choosing.
  3. Wrong: Yo soy confirmado la cita con el médico. — Right: Yo he confirmado la cita con el médico. — Spanish perfect tenses use haber, not ser: he confirmado, has confirmado, ha confirmado. Ser plus the participle makes a passive, not a perfect tense.
  4. Wrong: De niño, yo confirmé que todo está listo todos los días. — Right: De niño, yo confirmaba que todo está listo todos los días. — For a repeated habit in the past, use the imperfect (confirmaba), not the preterite. The preterite (confirmé) is for one finished action.
