El subjuntivo.

The Spanish subjunctive is the tense of wishes, doubts, future events that haven't happened yet, and recommendations — and the single biggest lever for top-grade marks at GCSE. You won't use it everywhere, but landing one or two well-placed subjunctives in your writing is a top-band marker. Focus on a few high-frequency trigger phrases and you'll be set.

When to use it

Triggered, not chosen

The subjunctive isn't a time — it's a mood. It shows up automatically after certain trigger phrases: wishes (ojalá, espero que), recommendations (es importante que), conjunctions that point to the future (cuando + future event, antes de que), and indirect commands (quiero que).

For GCSE, the most useful single rule is: "cuando + future event" needs the subjunctive. Cuando tenga dieciocho años, viajaré a Argentina ("When I'm 18, I'll travel to Argentina"). Learn that pattern plus ojalá and espero que, and you've got a top-mark sentence in every paragraph.

Model sentence

Cuando tenga dieciocho años, viajaré a Argentina.

When I'm 18, I'll travel to Argentina.

How to form it

The three-step recipe

Recipe

1Take the yo form of the present (e.g. hablo, como, tengo).

2Drop the final -o (habl-, com-, teng-).

3Add the opposite endings: -AR verbs take e-endings; -ER and -IR take a-endings.

-AR verbs

e.g. hablar — to speak

yo	hable
tú	hables
él / ella	hable
nosotros	hablemos
vosotros	habléis
ellos	hablen

-ER verbs

e.g. comer — to eat

yo	coma
tú	comas
él / ella	coma
nosotros	comamos
vosotros	comáis
ellos	coman

-IR verbs

e.g. vivir — to live

yo	viva
tú	vivas
él / ella	viva
nosotros	vivamos
vosotros	viváis
ellos	vivan

"Opposite endings": -AR verbs end in -a in the regular present (habla), so they "swap" to -e (hable). -ER and -IR verbs end in -e (come, vive), so they swap to -a (coma, viva).

Irregular yo-forms carry through

If the present-tense "yo" is irregular, that irregular stem appears throughout the subjunctive.

tener tengo →tenga, tengas, tenga, tengamos, tengáis, tengan

hacer hago →haga, hagas, haga, hagamos, hagáis, hagan

decir digo →diga, digas, diga, digamos, digáis, digan

venir vengo →venga, vengas, venga, vengamos, vengáis, vengan

poner pongo →ponga, pongas, ponga, pongamos, pongáis, pongan

salir salgo →salga, salgas, salga, salgamos, salgáis, salgan

conocer conozco →conozca, conozcas, conozca, conozcamos, conozcáis, conozcan

Pure irregulars (don't follow the recipe)

A handful of high-frequency verbs are irregular in the subjunctive in their own right. Memorise these by sight.

ser to besea, seas, sea, seamos, seáis, sean

ir to govaya, vayas, vaya, vayamos, vayáis, vayan

saber to knowsepa, sepas, sepa, sepamos, sepáis, sepan

haber to havehaya, hayas, haya, hayamos, hayáis, hayan

dar to givedé, des, dé, demos, deis, den

estar to beesté, estés, esté, estemos, estéis, estén

ver to seevea, veas, vea, veamos, veáis, vean

Trigger phrases

Phrases that summon the subjunctive

The subjunctive doesn't pick itself — it's triggered. Memorise these high-yield phrases for GCSE writing and your work will instantly read more sophisticated.

cuando + future eventwhen (something hasn't happened yet)

ojalá…I hope / let's hope…

espero que…I hope that…

quiero que…I want (someone) to…

es importante que…it's important that…

es necesario que…it's necessary that…

para que…so that…

antes de que…before…

Common mistakes

Using the regular present after a trigger

Once a trigger phrase appears, the next verb must be subjunctive. Cuando tengo 18 años, viajaré → Cuando tenga 18 años, viajaré.

Cuando + past / habit = no subjunctive

If cuando refers to a habit or a past event, you use the indicative. Cuando era pequeño, jugaba al fútbol (imperfect — habit, no subjunctive).

Yo-form irregulars carry through

If the regular "yo" is irregular (tengo, hago, salgo, conozco), the subjunctive uses that irregular stem. tena → tenga.

Don't translate "want him to" word-by-word

"I want him to come" = quiero que venga, not quiero él venir. Use que + subjunctive after a verb of wanting.

Ojalá always triggers it

Whatever follows ojalá is subjunctive. Ojalá llueva, ojalá vengas, ojalá tengamos suerte.

Spelling changes — "u" after g

To keep the hard sound, pagar becomes pague, not page. Similarly jugar → juegue, llegar → llegue.
