Common mistakes
- 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. Using the third-person form with yo is one of the most common beginner errors.
- 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. The accent marks the stressed vowel.
- Wrong: Treating informar and avisar as identical in every context. — Right: Informar means to inform, while avisar means to warn or notify in advance. — They overlap, but each has uses the other does not: informar fits sentences such as Informo al jefe de los cambios, while avisar belongs in a different sentence. Check the meaning you want before choosing.
- 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, has informado, ha informado. Ser plus the participle makes a passive, not a perfect tense.
- Wrong: De niño, yo informé a la policía del robo todos los días. — Right: De niño, yo informaba a la policía del robo todos los días. — For a repeated habit in the past, use the imperfect (informaba), not the preterite. The preterite (informé) is for one finished action.
