Common mistakes with iluminar
The errors learners actually make with iluminar in everyday use, each with the wrong form, the right form, and why it is wrong.
Mistake 1: Adding a reflexive pronoun that does not belong
- Wrong: Yo me ilumino la habitación con una vela.
- Right: Yo ilumino la habitación con una vela.
- Why: iluminar is not reflexive, so there is no pronoun to add: Yo ilumino la habitación con una vela. is the correct sentence.
Mistake 2: Using the infinitive as a conjugated form
- Wrong: Yo iluminar la habitación con una vela.
- Right: Yo ilumino la habitación con una vela.
- Why: The infinitive iluminar is the dictionary form, not a conjugated form. In a sentence with yo you need the present-tense form ilumino.
Mistake 3: Using the present tense for yesterday
- Wrong: Ayer, yo ilumino el escenario del teatro.
- Right: Ayer, yo iluminé el escenario del teatro.
- Why: Ayer means yesterday, so the action is finished and needs the preterite: Ayer, yo iluminé el escenario del teatro. — "Yesterday, I lighted up the theatre stage."
Mistake 4: Mixing up the gerund and the participle
- Wrong: Estoy iluminado la calle con farolas nuevas.
- Right: Estoy iluminando la calle con farolas nuevas.
- Why: After estar you need the gerund iluminando for the progressive. The participle iluminado goes with haber in the perfect tenses (he iluminado), never after estar.
Mistake 5: Using the él form for nosotros
- Wrong: Nosotros ilumina la habitación con una vela.
- Right: Nosotros iluminamos la habitación con una vela.
- Why: The person and the ending must match: nosotros takes iluminamos, while ilumina belongs to él and ella.
