How to Use the
Spanish Subjunctive

The subjunctive is used when Spanish expresses desire, doubt, emotion, uncertainty, or purpose. It is not a tense — it is a mood that appears across several tenses.

What triggers the subjunctive?

Look for phrases expressing desire (quiero que), emotion (me alegra que), doubt (no creo que), recommendation (es importante que), purpose (para que) and time in the future (cuando + subjunctive). These phrases require the next verb to be subjunctive.

Present subjunctive endings

Take the yo present indicative, drop the -o, and add the opposite vowel. -AR verbs get: -e, -es, -e, -emos, -éis, -en. -ER/-IR verbs get: -a, -as, -a, -amos, -áis, -an. Example: hablar → hablo → habl- → hable, hables, hable...

Key irregular forms

Ser (sea), estar (esté), ir (vaya), haber (haya), saber (sepa), dar (dé). These six must be memorised separately.

Example sentences

Quiero que estudies más — I want you to study more. Es importante que hables con él — It is important that you speak to him. Cuando llegues, llámame — When you arrive, call me.

GCSE and A-Level tip

At GCSE, include one subjunctive phrase in every extended writing task. At A-Level, vary between present and imperfect subjunctive and use complex triggers like sin que and a menos que for the highest marks.

Turn this into recall

Reading grammar explains the rules — but only active recall builds exam-ready memory. Practice typing these forms with instant feedback.

Frequently asked questions

What is the Spanish subjunctive?

The subjunctive is a mood expressing desire, doubt, emotion or uncertainty. It appears in subordinate clauses after triggers like querer que, es importante que, and para que.

How do you form the present subjunctive in Spanish?

Take the yo form of the present indicative, remove the -o, then add opposite vowel endings: -AR verbs use -e endings, -ER and -IR verbs use -a endings.

When do you use the subjunctive vs indicative?

Use the indicative for facts and certainty. Use the subjunctive after expressions of desire, doubt, emotion and purpose, and in time clauses with cuando referring to the future.
