The present tense vs the preterite

Learners often mix up the present and the preterite with informar. The rule is simple: the present is for habits, facts and what is happening now, while the preterite is for one finished action in the past. The three pairs below show the same idea in both tenses, so you can feel the difference.

Pair 1: present vs preterite

  • Present: "Yo informo al jefe de los cambios." — "I inform the boss about the changes."
  • Preterite: "Yo informé al jefe de los cambios." — "I informed the boss about the changes." The first sentence uses the present because it describes a habit or a present fact; the second uses the preterite because it describes a finished action. The verb is the same — only the tense changes the meaning.

Pair 2: present vs preterite

  • Present: "Él informa a los alumnos del examen." — "He/she informs the students about the exam."
  • Preterite: "Él informó a los alumnos del examen." — "He/she informed the students about the exam." The first sentence uses the present because it describes a habit or a present fact; the second uses the preterite because it describes a finished action. The verb is the same — only the tense changes the meaning.

Pair 3: present vs preterite

  • Present: "Nosotros informamos a la policía del robo." — "We inform the police about the robbery."
  • Preterite: "Nosotros informamos a la policía del robo." — "We informed the police about the robbery." The first sentence uses the present because it describes a habit or a present fact; the second uses the preterite because it describes a finished action. The verb is the same — only the tense changes the meaning.

Common mistakes

  1. Wrong: Vosotros informais a los alumnos del examen. — Right: Vosotros informáis a los alumnos del examen. — The vosotros present form carries a written accent: informáis, not informais.
  2. Wrong: Ayer, yo informo a la policía del robo. — Right: Ayer, yo informé a la policía del robo. — Ayer means yesterday, so it needs the preterite (informé), not the present (informo). The present is for now, not for yesterday.
  3. Wrong: Yo informa al jefe de los cambios. — Right: Yo informo al jefe de los cambios. — The person matters: informa is the él/ella/Ud. form, while the yo form is informo.
  4. Wrong: Yo soy informado a los alumnos del examen. — Right: Yo he informado a los alumnos del examen. — Spanish perfect tenses use haber, not ser: he informado. Ser plus the participle makes a passive, not a perfect tense.
