Common mistakes

  1. Wrong: Yo asegura a mi familia que todo va bien. — Right: Yo aseguro a mi familia que todo va bien. — The person matters: asegura is the él/ella/Ud. form, while the yo form is aseguro. Using the third-person form with yo is one of the most common beginner errors.
  2. Wrong: Treating asegurar and garantizar as identical in every context. — Right: Asegurar means to assure, to insure, while garantizar means to guarantee something. — They overlap, but each has uses the other does not: asegurar fits sentences such as Aseguro a mi familia que todo va bien, while garantizar belongs in a different sentence. Check the meaning you want before choosing.
  3. Wrong: Yo soy asegurado que el trabajo estará listo. — Right: Yo he asegurado que el trabajo estará listo. — Spanish perfect tenses use haber, not ser: he asegurado, has asegurado, ha asegurado. Ser plus the participle makes a passive, not a perfect tense.
  4. Wrong: De niño, yo aseguré a mis amigos que llegaré a tiempo todos los días. — Right: De niño, yo aseguraba a mis amigos que llegaré a tiempo todos los días. — For a repeated habit in the past, use the imperfect (aseguraba), not the preterite. The preterite (aseguré) is for one finished action.
