Common mistakes with fortalecerse

The errors learners actually make with fortalecerse in everyday use, each with the wrong form, the right form, and why it is wrong.

Mistake 1: Forgetting the reflexive pronoun

  • Wrong: Yo fortalezco con el ejercicio diario.
  • Right: Yo me fortalezco con el ejercicio diario.
  • Why: fortalecerse is reflexive, so the pronoun is part of the verb: Yo me fortalezco con el ejercicio diario.. Without me the sentence is incomplete.

Mistake 2: Using the infinitive as a conjugated form

  • Wrong: Yo fortalecerse con el ejercicio diario.
  • Right: Yo me fortalezco con el ejercicio diario.
  • Why: The infinitive fortalecerse is the dictionary form, not a conjugated form. In a sentence with yo you need the present-tense form fortalezco.

Mistake 3: Using the present tense for yesterday

  • Wrong: Ayer, yo me fortalezco con la comida sana.
  • Right: Ayer, yo me fortalecí con la comida sana.
  • Why: Ayer means yesterday, so the action is finished and needs the preterite: Ayer, yo me fortalecí con la comida sana. — "Yesterday, I grew stronger with healthy food."

Mistake 4: Mixing up the gerund and the participle

  • Wrong: Me estoy fortalecido después de la enfermedad.
  • Right: Me estoy fortaleciendo después de la enfermedad.
  • Why: After estar you need the gerund fortaleciendo for the progressive. The participle fortalecido goes with haber in the perfect tenses (me he fortalecido), never after estar.

Mistake 5: Using the él form for nosotros

  • Wrong: Nosotros nos fortalece con el ejercicio diario.
  • Right: Nosotros nos fortalecemos con el ejercicio diario.
  • Why: The person and the ending must match: nosotros takes fortalecemos, while fortalece belongs to él and ella.
