Common mistakes

  1. Wrong: Yo pronostica lluvia para mañana. — Right: Yo pronostico lluvia para mañana. — The person matters: pronostica is the él/ella/Ud. form, while the yo form is pronostico. Using the third-person form with yo is one of the most common beginner errors.
  2. Wrong: Espero que yo pronostice lluvia para mañana. — Right: Espero que yo pronostique lluvia para mañana. — Spelling change: this verb is a -car verb: c becomes qu before e, so the preterite first person is pronostiqué and the present subjunctive is pronostique, so the present subjunctive is pronostique, never pronostice.
  3. Wrong: Treating pronosticar and predecir as identical in every context. — Right: Pronosticar means to forecast, while predecir means to predict. — They overlap, but each has uses the other does not: pronosticar fits sentences such as Pronostico lluvia para mañana, while predecir belongs in a different sentence. Check the meaning you want before choosing.
  4. Wrong: Yo soy pronosticado una victoria del equipo. — Right: Yo he pronosticado una victoria del equipo. — Spanish perfect tenses use haber, not ser: he pronosticado, has pronosticado, ha pronosticado. Ser plus the participle makes a passive, not a perfect tense.
  5. Wrong: De niño, yo pronostiqué sol para el fin de semana todos los días. — Right: De niño, yo pronosticaba sol para el fin de semana todos los días. — For a repeated habit in the past, use the imperfect (pronosticaba), not the preterite. The preterite (pronostiqué) is for one finished action.
