Common mistakes

  1. Wrong: Ellos malgasta el dinero — Right: Ellos malgastan el dinero — Ellos needs the ellos form malgastan. The singular malgasta belongs with él, ella or a singular noun.
  2. Wrong: Ayer, yo malgasto — Right: Ayer, yo malgasté — The present tense cannot describe a finished action yesterday. Ayer forces the preterite, so the form must change to malgasté.
  3. Wrong: De niño, yo malgasté todos los días. — Right: Todos los días, yo malgastaba — For a repeated habit in the past, use the imperfect (malgastaba), not the preterite. The preterite (malgasté) is for one finished action.
  4. Wrong: Yo soy malgastado su tiempo. — Right: Yo he malgastado su tiempo. — Spanish perfect tenses use haber, not ser: he malgastado, has malgastado, ha malgastado. Ser plus the participle makes a passive, not a perfect tense.
  5. Wrong: Espero que él malgasta el dinero. — Right: Espero que él malgaste el dinero. — After espero que, Spanish needs the subjunctive: malgaste. The indicative malgasta is wrong here.
