Spanish subjunctive

The subjunctive isn’t a tense. It’s a mood, a way of marking that a verb is wished for, doubted, felt about or not yet real, rather than stated as fact. It almost always appears after que, in a second clause with a different subject.

Switch the trigger, watch the mood

Quiero que vengas mañana.

Subjunctive. Wanting someone else to do something always takes the subjunctive.

How to form it

  1. Start from the yo form of the present: hablo, como, tengo, conozco.
  2. Drop the final -o: habl-, com-, teng-, conozc-.
  3. Add the “opposite vowel” endings: -ar verbs take e, -er/-ir verbs take a.

Because it starts from the yo form, every yo-go and -zco irregularity carries through: hacer → haga, decir → diga, poner → ponga, conocer → conozca. Spelling changes keep the sound: buscar → busque, llegar → llegue, empezar → empiece.

Same subject? Use the infinitive

If both clauses share a subject, Spanish uses an infinitive instead of que + subjunctive: Quiero ir (I want to go) vs Quiero que vayas (I want you to go).

Conjunctions that always take the subjunctive

para que, antes de que, sin que, a menos que, con tal de que, en caso de que. And cuando, hasta que, en cuanto, tan pronto como take it when the action is still in the future: Te llamo cuando llegue.

Frequently asked questions

How do you form the present subjunctive in Spanish?

Take the yo form of the present indicative, drop the -o, and add the “opposite” endings: -e, -es, -e, -emos, -éis, -en for -ar verbs and -a, -as, -a, -amos, -áis, -an for -er/-ir verbs. Hablo → hable, tengo → tenga, conozco → conozca.

When do you use the subjunctive in Spanish?

Mainly in a clause introduced by que when the main clause expresses a wish, emotion, doubt, denial, necessity or an impersonal judgement, and the two clauses have different subjects: Quiero que vengas. Also after certain conjunctions (para que, antes de que, a menos que) and with future-time cuando.

What does WEIRDO stand for?

WEIRDO is a mnemonic for subjunctive triggers: Wishes, Emotions, Impersonal expressions, Recommendations, Doubt/Denial and Ojalá.

Which verbs are irregular in the present subjunctive?

Six verbs don’t follow the yo-form rule: ser (sea), estar (esté), ir (vaya), saber (sepa), haber (haya) and dar (dé). Remember them as DISHES.
