The subjunctive has a reputation as the final boss of Spanish grammar, which keeps learners avoiding it long past the point where they need it. It turns up constantly in ordinary speech, and avoiding it makes you sound stilted rather than safe.
It is also more tractable than its reputation suggests.
It is a mood, not a tense
Tenses tell you when. Moods tell you what kind of statement you are making. Spanish has three: indicative for facts, imperative for commands, subjunctive for everything that is not being asserted as real.
The indicative states what is. The subjunctive handles what is wanted, doubted, feared, requested, or merely hypothetical: the things that exist in someone’s head rather than in the world.
One pair makes it concrete. Sé que viene — "I know he is coming," a fact, indicative. Espero que venga — "I hope he comes," a wish that may not happen, subjunctive.
The arrival has not changed. Your relationship to it has.
WEIRDO: the six triggers
The standard memory aid is WEIRDO, and it is genuinely one of the good ones. Each letter is a category of expression that takes the subjunctive in the clause after que.
W — Wishes
Wanting, preferring, demanding, hoping.
- Quiero que vengas — I want you to come.
- Prefiero que lo hagas tú — I prefer that you do it.
- Espero que estés bien — I hope you are well.
E — Emotions
Any reaction to something: gladness, regret, fear, surprise.
- Me alegro de que estés aquí — I am glad you are here.
- Siento que no puedas venir — I am sorry you cannot come.
- Temo que sea demasiado tarde — I fear it may be too late.
Note that the thing itself may be perfectly real, since you know they are here. The subjunctive is doing something else: marking that you are reacting rather than reporting.
I — Impersonal expressions
Es + adjective + que, where the adjective is a judgement.
- Es importante que estudies — It is important that you study.
- Es posible que llueva — It may rain.
- Es mejor que te vayas — It is better that you go.
The exception matters: impersonal expressions asserting certainty take the indicative. Es verdad que viene. Es obvio que lo sabe. If it claims something is true, it is not subjunctive territory.
R — Recommendations and requests
- Te recomiendo que lo pruebes — I recommend you try it.
- Le pido que espere — I ask him to wait.
- Sugiero que hablemos mañana — I suggest we talk tomorrow.
D — Doubt and denial
- Dudo que sea verdad — I doubt it is true.
- No creo que venga — I do not think he is coming.
- Niego que haya pasado — I deny it happened.
The flip is instructive. No creo que venga is subjunctive, but creo que viene is indicative, because believing something asserts it, while disbelieving it does not. Negation is doing the work.
O — Ojalá
Ojalá always takes the subjunctive, without exception. Ojalá que llueva — "I hope it rains," or wistfully, "if only it would." It comes from Arabic law šāʾ Allāh, "if God wills," a small fossil of eight centuries of Al-Andalus sitting in everyday Spanish.
The structural giveaway
Nearly every subjunctive sentence has the same shape: one clause, then que, then a different subject doing something.
That subject change is the tell. Quiero ir — I want to go, same subject, plain infinitive, no subjunctive. Quiero que vayas — I want you to go, subject changes, subjunctive appears.
If the subject does not change, you almost always want an infinitive instead.
What does not take it
Useful to know, since over-applying it is the next mistake after avoiding it.
- Statements of fact: Sé que está aquí.
- Belief in the affirmative: Creo que tiene razón.
- Certainty: Es cierto que funciona.
- Same-subject constructions: Quiero comer, not quiero que coma.
How to actually get it
- Learn the trigger phrases as chunks. Not "the subjunctive after verbs of volition," but espero que, ojalá, es importante que — as single units that come pre-loaded with what follows.
- Start with the handful you will actually say. Espero que, quiero que, no creo que, ojalá. That is most of your daily need.
- Use it before you have mastered it. Avoiding the subjunctive is more noticeable than using it clumsily.
- Notice it in input. Once you know the shape, you will hear it everywhere, and that is when it starts becoming automatic.
Our conversation practice is a low-stakes place to get it wrong repeatedly, which is the only route to getting it right. For the other two classic Spanish confusions, see ser vs estar and por vs para.
Facts take the indicative. Everything wished, doubted, feared or requested takes the subjunctive. Learn six phrases and you have most of it.
