Common mistakes

  1. Wrong: Yo aterroriza a los niños con la película. — Right: Yo aterrorizo a los niños con la película. — The person matters: aterroriza is the él/ella/Ud. form, while the yo form is aterrorizo. Using the third-person form with yo is one of the most common beginner errors.
  2. Wrong: Ayer, yo aterrorizé a la familia con amenazas. — Right: Ayer, yo aterroricé a la familia con amenazas. — Spelling change: z becomes c before e, so the preterite is aterroricé, never aterrorizé.
  3. Wrong: Treating aterrorizar and asustar as identical in every context. — Right: Aterrorizar means to terrify, while asustar means to frighten someone. — They overlap, but each has uses the other does not: aterrorizar fits sentences such as Aterrorizo a los niños con la película, while asustar belongs in a different sentence. Check the meaning you want before choosing.
  4. Wrong: Yo soy aterrorizado al pueblo con la tormenta. — Right: Yo he aterrorizado al pueblo con la tormenta. — Spanish perfect tenses use haber, not ser: he aterrorizado, has aterrorizado, ha aterrorizado. Ser plus the participle makes a passive, not a perfect tense.
  5. Wrong: De niño, yo aterroricé a la familia con amenazas todos los días. — Right: De niño, yo aterrorizaba a la familia con amenazas todos los días. — For a repeated habit in the past, use the imperfect (aterrorizaba), not the preterite. The preterite (aterroricé) is for one finished action.
