Present Subjunctive Spanish: How to Form It in Three Steps (and the Six Irregulars)

Present subjunctive Spanish forms all come from one place: the yo form of the present. Take hablo, drop the -o, add the opposite vowel, and you have hable. That’s the whole procedure, and it works for almost every verb you know.

One thing before the forms: the subjunctive is a mood, not a tense. It doesn’t place an action in time; it marks it as wished for, doubted or not yet real. Here we’re dealing with how to build it, with a short section on when to use it near the end.

How present subjunctive Spanish endings work

Spanish subjunctive conjugation starts from yo, and it takes three steps:

1. Conjugate the verb in the present, yo form: hablo, como, vivo.
2. Drop the final -o: habl-, com-, viv-.
3. Add the ending with the opposite vowel: -ar verbs take e, -er and -ir verbs take a.

“Opposite vowel” is the part to remember. In the regular present, -ar verbs live on a (habla) and -er/-ir verbs live on e (come, vive). The subjunctive swaps them.

Person	hablar	comer	vivir
yo	hable	coma	viva
tú, vos	hables	comas	vivas
él, ella, usted	hable	coma	viva
nosotros	hablemos	comamos	vivamos
vosotros (Spain)	habléis	comáis	viváis
ellos, ellas, ustedes	hablen	coman	vivan

Regular endings of the Spanish subjunctive conjugation: -e for -ar verbs, -a for -er and -ir verbs.

Notice that yo and él share a form (hable), so context or a pronoun tells them apart. About vos: according to the RAE’s guide to voseo, in Argentina the tú form and a vos form alternate in the present subjunctive (que vos pienses, que vos pensés), while Uruguay and Paraguay prefer the tú form.

Irregular yo forms carry over: tenga, haga, conozca

Here’s why starting from yo matters. Many common verbs have an irregular yo in the present, and the subjunctive simply inherits it. You don’t need a new list.

Verb	yo (present)	Subjunctive
tener	tengo	tenga
hacer	hago	haga
decir	digo	diga
poner	pongo	ponga
salir	salgo	salga
venir	vengo	venga
traer	traigo	traiga
oír	oigo	oiga
conocer	conozco	conozca
ver	veo	vea

If you tried to build these from the infinitive, you’d get tena or hacea. From yo, they come out right every time, and the g or zc stays in all six persons: tengamos, conozcan.

Stem changing verbs in the present subjunctive

Stem changes come back in the subjunctive with the same “boot” shape as the present: every person changes except nosotros and vosotros. Pensar gives piense, volver gives vuelva.

The -ir verbs add one detail. In nosotros and vosotros, they still change, to a smaller vowel: e becomes i, o becomes u.

	pensar (-ar)	dormir (-ir)	sentir (-ir)	pedir (-ir)
yo	piense	duerma	sienta	pida
tú	pienses	duermas	sientas	pidas
él, ella	piense	duerma	sienta	pida
nosotros	pensemos	durmamos	sintamos	pidamos
ellos	piensen	duerman	sientan	pidan

The full picture of these verbs, with every pattern, is in Spanish stem-changing verbs. Forms for each one are on the pages for pensar, volver, dormir, sentir and pedir.

Spelling changes: -car, -gar, -zar, -ger, -guir

Some verbs change a letter, not a sound. When the ending switches vowel, Spanish spelling has to adjust to keep the same consonant sound:

Ending	Change	Example
-car	c → qu	buscar → busque
-gar	g → gu	llegar, pagar → llegue, pague
-zar	z → c	empezar → empiece
-ger	g → j	escoger → escoja
-guir	gu → g	seguir → siga

Busce would be pronounced “BOOS-seh,” so the c becomes qu to keep the hard k sound. Same logic for llegue: the silent u keeps the g hard. The car, gar, zar verbs guide covers the preterite version of the same rule.

Irregular subjunctive verbs: DISHES

Only six verbs ignore the three steps. The word DISHES keeps them together: dar, ir, ser, haber, estar, saber. Their yo forms (doy, voy, soy, he, estoy, sé) don’t end in -o the usual way, so the procedure has nothing to start from.

Verb	Subjunctive	Example
dar	dé, des, dé, demos, den	Dile que me dé su número.
ir	vaya, vayas, vaya, vayamos, vayan	Que te vaya bien en el examen.
ser	sea, seas, sea, seamos, sean	No creo que sea tan difícil.
haber	haya, hayas, haya, hayamos, hayan	Dudo que haya mesa libre.
estar	esté, estés, esté, estemos, estén	Espero que estés bien.
saber	sepa, sepas, sepa, sepamos, sepan	No quiero que sepan nada.

Two of them carry accent marks you can’t skip. Dé (give) needs it to stand apart from de (of). Esté and estés keep the stress of estar: without the mark, este is “this.”

These are the irregular subjunctive verbs people mean when they say the subjunctive is hard. Everything else follows the three steps.

When you’ll need it: subjunctive or indicative, the short version

Start with five triggers you’ll hear all the time:

Trigger	Meaning	Example
quiero que	I want (someone else) to	Quiero que vengas.
ojalá	I hope	Ojalá haga sol.
es importante que	it’s important that	Es importante que duermas bien.
no creo que	I don’t think	No creo que sea difícil.
cuando + future	when (it hasn’t happened yet)	Cuando llegues, avísame.

Two pairs trip up English speakers. Creo que tienes razón uses the indicative, because you’re stating what you believe. Add no, and it flips: no creo que tengas razón. And si never takes the present subjunctive: si tengo tiempo, te ayudo, exactly like English “if I have time.”

Cuando catches people too. English says “when you get there,” in the present, so learners write cuando llegas. For something still in the future, Spanish wants cuando llegues. For a habit, it’s back to the indicative: cuando llego a casa, me ducho.

The big picture (the three moods, the places where the subjunctive shows up and its four tenses) is in the Spanish subjunctive guide. To practice the ones above right now, try the Spanish subjunctive exercises: 20 sentences with audio and a worksheet with answers.

Present subjunctive in Spanish examples you’ll hear

Some subjunctive sentences are so common they work like set phrases. You’ll hear these every week:

The pattern is que + subjunctive, with “I hope” left out. These present subjunctive in Spanish examples are worth learning as whole chunks.

To drill the forms on their own, the conjugation practice in subjunctive mode gives you a verb and a person, and checks what you type.

Now try the procedure on a verb we haven’t touched: elegir (to choose). The yo form is elijo. Drop the -o: elij-. Add the opposite vowel: elija, elijas, elijamos. The stem change and the spelling change both came along for free, because they were already in elijo. Check your answer on the elegir page.
