The present describes things that happen regularly, as a habit or routine.

The present tense vs the closest tenses

Present — habit or general fact vs Preterite — one finished occasion

The present describes a habit, a routine or a general fact — something that happens again and again or that is true in general. The preterite reports one finished occasion in the past. Use the present when the action repeats or is still true, and the preterite when you are telling what happened once, on a specific day.

  • Present — habit or general fact: {'pre_es': 'Cada día, ', 'pre_en': 'Every day, '}yo muerdo una manzana verde — "I bite a green apple"
  • Preterite — one finished occasion: {'pre_es': 'Ayer, ', 'pre_en': 'Yesterday, '}yo mordí una manzana verde — "I bit a green apple"

Present — now vs Imperfect — a past habit or background

The present talks about now. The imperfect talks about the past as a background — a repeated habit, an ongoing situation, something that used to happen. If you can add "used to" in English, the imperfect is usually the right choice; if it is happening now or always, use the present.

  • Present — now: {}tú muerdes el bocadillo con hambre — "You bite the sandwich hungrily"
  • Imperfect — a past habit or background: {}tú mordías el bocadillo con hambre — "You used to bite the sandwich hungrily"

Present — now or a fixed plan vs Future — what will happen

The present describes what happens now, what you do regularly, or a plan that is already fixed. The future describes what will happen later — a promise, a prediction, a plan that is not yet under way. Spanish often uses the present for near-future plans, but the future is the form for a clear statement about tomorrow.

  • Present — now or a fixed plan: {'subj_es': 'Mi amigo', 'subj_en': 'My friend'}él muerde la cuerda con los dientes — "He bites the rope with his teeth"
  • Future — what will happen: {'subj_es': 'Mi amigo', 'subj_en': 'My friend'}él morderá la cuerda con los dientes — "He will bite the rope with his teeth"

Common mistakes with morder in the present tense

These are the errors learners actually make with morder in the present tense. Each one shows the wrong form, the right form, and why the right form is right.

✗ *Yo mordo una manzana verde.

✓ Correct: Yo muerdo una manzana verde.

morder is a stem-changing verb (o → ue): the stem vowel changes in the stressed present forms, so the yo form is muerdo, not mordo.

✗ *Tú muerde el bocadillo con hambre.

✓ Correct: Tú muerdes el bocadillo con hambre.

The tú form and the él form are different: tú takes muerdes, él takes muerde.

✗ *Cada día, yo mordí la cuerda con los dientes

✓ Correct: Cada día, yo muerdo la cuerda con los dientes

Cada día describes a habit, so it needs the present, not the preterite.

✗ *Vosotros mordeis a su hermano en el brazo.

✓ Correct: Vosotros mordéis a su hermano en el brazo.

The vosotros present form carries a written accent: mordéis, not mordeis.
