The Spanish Subjunctive: When to Use It and How to Form It
The Spanish subjunctive (el subjuntivo) is not a tense, it is a mood. You use it to talk about things that are wished for, doubted, felt, or not yet real, rather than plain facts. It scares learners because English barely has it, but it runs on two simple questions: does the sentence carry a trigger like a wish or a doubt, and are the two halves talking about different people? Answer those and you know to use it. This guide gives you the WEIRDO triggers that switch it on, the endings for every verb group, the irregulars and spelling changes that actually matter, and real example sentences with audio you can copy out loud.

When to use it: the WEIRDO triggers
The subjunctive almost always shows up in the second half of a sentence, after the word que, once a trigger in the first half calls for it. The trigger is a word or phrase that expresses something other than plain fact. A well-known memory aid, WEIRDO, catches nearly all of them:
| Letter | Trigger type | Typical phrases |
|---|---|---|
| W | Wishes | querer que, esperar que, desear que |
| E | Emotions | alegrarse de que, temer que, sentir que |
| I | Impersonal expressions | es importante que, es necesario que, es posible que |
| R | Recommendations, requests | recomendar que, pedir que, sugerir que |
| D | Doubt, denial | dudar que, no creer que, no pensar que |
| O | Ojala | ojala (que) |
There is one more condition that beginners often miss: the two clauses usually need different subjects. Quiero que vengas (I want you to come) uses the subjunctive because I want and you come are two different people. But quiero venir (I want to come) is one person, so it stays as a plain infinitive, no subjunctive. Same subject, no que, no subjunctive.
How to form the present subjunctive
The formation rule is beautifully mechanical and works for almost every verb. Three steps:
- Take the yo form of the present indicative: hablo, como, vivo.
- Drop the final -o: habl-, com-, viv-.
- Add the opposite vowel endings. For -ar verbs, switch to e endings. For -er and -ir verbs, switch to a endings.
Starting from the yo form is the trick that saves you, because any irregularity in the yo form (like tengo from tener) is carried straight into every subjunctive form: tenga, tengas, tenga, and so on. Here is hablar laid out with its endings.
| Persona | Ending (-ar) | hablar |
|---|---|---|
| yo | -e | hable |
| tu | -es | hables |
| el / ella / usted | -e | hable |
| nosotros | -emos | hablemos |
| vosotros | -eis | hableis |
| ellos / ustedes | -en | hablen |

The three verb groups side by side
See how -ar verbs take e endings while -er and -ir verbs take a endings. That vowel flip is the heart of the whole system.
| Persona | hablar (-ar) | comer (-er) | vivir (-ir) |
|---|---|---|---|
| yo | hable | coma | viva |
| tu | hables | comas | vivas |
| el / ella / usted | hable | coma | viva |
| nosotros | hablemos | comamos | vivamos |
| vosotros | hableis | comais | vivais |
| ellos / ustedes | hablen | coman | vivan |
Irregulars and spelling changes
Two groups of verbs need special attention. First, six common verbs are fully irregular and do not follow the yo-form rule. A popular mnemonic for them is DISHES.
| Verb | Meaning | yo form | Full set |
|---|---|---|---|
| dar | to give | de | de, des, de, demos, deis, den |
| ir | to go | vaya | vaya, vayas, vaya, vayamos, vayais, vayan |
| ser | to be | sea | sea, seas, sea, seamos, seais, sean |
| haber | to have (aux) | haya | haya, hayas, haya, hayamos, hayais, hayan |
| estar | to be | este | este, estes, este, estemos, esteis, esten |
| saber | to know | sepa | sepa, sepas, sepa, sepamos, sepais, sepan |
Second, verbs ending in -car, -gar and -zar change their spelling so the consonant keeps its original sound before the e endings. This is a spelling rule, not a new pronunciation to learn.
| Ending | Changes to | Example |
|---|---|---|
| -car | -que | buscar becomes busque |
| -gar | -gue | llegar becomes llegue |
| -zar | -ce | empezar becomes empiece |
Stem-changing verbs keep their stem change too, again because you build from the yo form. Tener gives tenga, poder gives pueda, and pedir gives pida. If you want the full backdrop, our guide to verb conjugation in Spanish shows how these patterns run across the tenses.

Common mistakes to avoid
- Forgetting the different-subject rule. With one subject, use the infinitive: quiero comer (I want to eat), not quiero que coma. The subjunctive needs two different people, as in quiero que comas (I want you to eat).
- Using it after certainty. Creer que and pensar que in the positive state a belief, so they take the indicative: creo que viene (I think he is coming). Only the negative, no creo que venga, flips to the subjunctive because it adds doubt.
- Mixing up indicative and subjunctive endings. Remember the vowel flip. Habla is he speaks (indicative), hable is that he speak (subjunctive). One letter changes the whole meaning.
- Dropping the yo-form irregularity. It is tenga, not tena, and salga, not sala, because the subjunctive keeps whatever the yo form does.
Once the present subjunctive feels solid, the natural next steps are the present tense in Spanish to lock in the indicative you build from, and the subjunctive in French if you are studying more than one language.

Frequently asked questions
When do you use the subjunctive in Spanish?
Use the subjunctive when a sentence expresses a wish, an emotion, an impersonal judgment, a recommendation or request, doubt or denial, or the word ojala. A common memory aid is WEIRDO: Wishes, Emotions, Impersonal expressions, Recommendations, Doubt and Denial, and Ojala. Most of the time it appears in a second clause after que, when the subject of the two clauses is different, as in quiero que vengas, I want you to come.
How do you form the present subjunctive in Spanish?
Start from the yo form of the present indicative, drop the final -o, and add the opposite vowel endings. For -ar verbs add -e, -es, -e, -emos, -eis, -en, so hablar becomes hable. For -er and -ir verbs add -a, -as, -a, -amos, -ais, -an, so comer becomes coma and vivir becomes viva. Because you build from the yo form, most irregular verbs keep their irregularity, as in tener, tengo, tenga.
What are the irregular subjunctive verbs in Spanish?
Six verbs are fully irregular and worth memorizing, often remembered as DISHES: dar (de), ir (vaya), ser (sea), haber (haya), estar (este), and saber (sepa). Verbs ending in -car, -gar and -zar also change spelling to keep their sound: buscar becomes busque, llegar becomes llegue, and empezar becomes empiece.
What is the difference between the indicative and the subjunctive?
The indicative states facts and things you are sure about, while the subjunctive expresses wishes, doubts, emotions and situations that are not presented as real. Se que hablas espanol (I know you speak Spanish) uses the indicative because it is a fact, but espero que hables espanol (I hope you speak Spanish) uses the subjunctive because it is a wish, not a certainty.
Does ojala always take the subjunctive?
Yes. Ojala means hopefully or I hope, and it always triggers the subjunctive, with or without que. Ojala llueva means I hope it rains, and ojala que ganemos means I hope we win. The word itself comes from an Arabic phrase meaning God willing, which is a useful hook for remembering that it points at something wished for rather than certain.
