Common mistakes with calentar

The errors learners actually make with calentar, each with the wrong form, the right form, and why the right form is right.

✗ *Yo calento el motor antes de salir.

✓ Correct: Yo caliento el motor antes de salir.

calentar is a stem-changing verb (e → ie): the stem vowel changes in the stressed present forms, so the yo form is caliento, not calento.

✗ *Espero que él calienta el motor antes de salir

✓ Correct: Espero que él caliente el motor antes de salir

After espero que, Spanish requires the subjunctive: Espero que él caliente el motor antes de salir — not the indicative Espero que él calienta el motor antes de salir.

✗ *Ayer, yo caliento la casa con la chimenea

✓ Correct: Ayer, yo calenté la casa con la chimenea

Ayer points to a finished action in the past, so it needs the preterite: Ayer, yo calenté la casa con la chimenea.

✗ *De niño, yo calenté la leche en el microondas todos los días

✓ Correct: De niño, yo calentaba la leche en el microondas todos los días

For a repeated habit in the past, use the imperfect, not the preterite: De niño, yo calentaba la leche en el microondas todos los días.

✗ *Yo caliento en la sopa en la cacerola.

✓ Correct: Yo caliento la sopa en la cacerola.

calentar takes this complement directly, with no preposition: Yo caliento la sopa en la cacerola.
