Common mistakes with jactarse
The errors learners actually make with jactarse, each with the wrong form, the right form, and why it is wrong.
Mistake 1: Forgetting the reflexive pronoun
- Wrong: Yo jacto de su nuevo coche.
- Right: Yo me jacto de su nuevo coche.
- Why: jactarse is reflexive, so the pronoun is part of the verb: Yo me jacto de su nuevo coche.. Without me the sentence is incomplete, and it sounds as if the action happens to someone else.
Mistake 2: Dropping the accent on the vosotros form
- Wrong: Vosotros os jactais de su nuevo coche.
- Right: Vosotros os jactáis de su nuevo coche.
- Why: The vosotros form jactáis carries a written accent. Without it the word is misspelled, and in writing the accent is part of the form.
Mistake 3: Using the present tense for yesterday
- Wrong: Ayer, yo me jacto de sus notas en la escuela.
- Right: Ayer, yo me jacté de sus notas en la escuela.
- Why: Ayer means yesterday, so the action is finished and needs the preterite. The present tense is for habits and routines, not for yesterday: Ayer, yo me jacté de sus notas en la escuela. — "Yesterday, I boasted about his school grades."
Mistake 4: Mixing up the gerund and the participle
- Wrong: Me estoy jactado de su trabajo en la oficina.
- Right: Me estoy jactando de su trabajo en la oficina.
- Why: After estar you need the gerund jactando for the progressive. The participle jactado goes with haber in the perfect tenses (me he jactado), never after estar.
Mistake 5: Using the él form for nosotros
- Wrong: Nosotros nos jacta de su nuevo coche.
- Right: Nosotros nos jactamos de su nuevo coche.
- Why: The person and the ending must match: nosotros takes jactamos, while jacta belongs to él and ella. Check the person first, then choose the form.
