Lesson 32: Subjunctive after verbs of will and influence

Part 1: The big idea — one person wills, another acts

I want YOU to do something. Two different subjects → the second verb goes into subjuntivo.

English has a trick that hides this: instead of saying "I want that you eat", we collapse it into "I want you to eat". Spanish doesn't allow that shortcut. Whenever the subject of the second action is different from the subject of the main verb (and the main verb is one of will/influence), you MUST use que + subjunctive.

English	Spanish
I want to come. (same subject — me wanting, me coming)	Quiero venir. (infinitive)
I want you to come. (different subjects — me wanting, you coming)	Quiero que vengas. (que + subjunctive)
She asks us to be quiet.	Ella pide que (nos) callemos.
The teacher tells us to open the book.	El profesor manda que abramos el libro.

The two-subject rule: If both actions belong to the same person → infinitive, no que. If the actions belong to different people → que + subjuntivo.

One subject (infinitive)	Two subjects (que + subjuntivo)
Quiero estudiar. — I want to study.	Quiero que estudies. — I want you to study.
Espero llegar a tiempo. — I hope to arrive on time.	Espero que llegues a tiempo. — I hope you arrive on time.
Prefiero quedarme en casa. — I prefer to stay home.	Prefiero que te quedes en casa. — I prefer that you stay home.

Trap #1: Never say Quiero que yo vaya — same subject means Quiero ir. Trap #2: English drops "that" — "I want you to come" has no visible "that". Spanish que is never optional: Quiero que vengas, never Quiero vengas. Trap #3: Don't slip back into indicative. Espero que vienes is wrong — esperar que always takes subjuntivo: Espero que vengas.

Part 2: Triggers — the verbs that flip the switch

All of these verbs express will, desire, request, advice, command, permission, or prohibition. After them, when the subject changes and you cross a que — only subjuntivo.

Group 1: Wanting and hoping

Spanish	English	Example
querer que	to want (somebody) to	Quiero que vengas. — I want you to come.
desear que	to wish that	Deseo que tengas suerte. — I wish you luck.
preferir que	to prefer that	Prefiero que lo hagas tú. — I'd rather you do it.
esperar que	to hope that	Espero que estés bien. — I hope you're well.

Esperar is a double agent. "To hope" → subjuntivo. "To wait for" → plain object: Espero a María (I'm waiting for María).

Group 2: Requesting, advising, commanding

Spanish	English	Example
pedir que	to ask (somebody) to	Te pido que me ayudes. — I'm asking you to help me.
rogar que	to beg that	Te ruego que me escuches. — I beg you to listen to me.
suplicar que	to plead that	Le suplico que me perdone. — I plead with you to forgive me.
mandar que	to order that	El jefe manda que trabajemos. — The boss orders us to work.
ordenar que	to order (formal)	El juez ordena que se calle. — The judge orders him to be quiet.
exigir que	to demand that	Exijo que me digan la verdad. — I demand that you tell me the truth.
sugerir que	to suggest that	Sugiero que descansemos. — I suggest we rest.
aconsejar que	to advise (somebody) to	Te aconsejo que estudies más. — I advise you to study more.
recomendar que	to recommend that	Recomiendo que pruebes la paella. — I recommend you try the paella.

Group 3: Permitting and prohibiting

Spanish	English	Example
prohibir que	to forbid that	Prohíben que fumemos aquí. — They forbid us to smoke here.
permitir que	to allow that	No permito que me hables así. — I won't allow you to talk to me like that.
dejar que	to let (somebody)	Deja que lo intente. — Let him try.
hacer que	to make (somebody) do	Haz que se sientan bien. — Make them feel good.

Note: prohíbo, prohíbes, prohíbe, prohibimos, prohibís, prohíben — the tilde splits the i from the o.

Group 4: Impersonal expressions of necessity

After these, always subjuntivo if there's a subject. Without a subject — plain infinitive, expressing a general rule.

Spanish	English	Example
es necesario que	it's necessary that	Es necesario que vayas al médico. — You need to see a doctor.
es preciso que	it's needed that	Es preciso que actuemos ya. — We need to act now.
hace falta que	it's needed that	Hace falta que estudies más. — You need to study more.
es importante que	it's important that	Es importante que llegues a tiempo. — It's important you arrive on time.
es preferible que	it's preferable that	Es preferible que descanses. — It's better you rest.
es mejor que	it's better that	Es mejor que no digas nada. — Better that you say nothing.
es urgente que	it's urgent that	Es urgente que vengas. — It's urgent that you come.

Without subject (infinitive)	With subject (que + subjuntivo)
Es necesario estudiar. — One has to study.	Es necesario que estudies. — You need to study.
Es importante llegar a tiempo. — It's important to be on time.	Es importante que llegues a tiempo. — It's important that you arrive on time.

Group 5: Pure wishing — ojalá

Ojalá (que) comes from Arabic wa-šā' allāh — "and God willing". It means "I hope / I wish / if only". It always triggers subjuntivo, and the que is optional. Ojalá is the one trigger that needs no main clause and no different subject — it stands alone.

Spanish	English
Ojalá llueva.	I hope it rains. / If only it would rain.
Ojalá (que) vengas mañana.	I hope you come tomorrow.
Ojalá tengas razón.	I hope you're right.
Ojalá no llegue tarde.	I hope he doesn't arrive late.
