Imperfecto de subjuntivo: otros usos

Quería que vinieras a la fiesta.I wanted you to come to the party.

You already know the imperfect subjunctive from the imaginary si clauses. It does a lot more than that: it is the tense Spanish reaches for whenever a subjunctive trigger sits in the past or the conditional, and it also shows up in a few set patterns (quisiera, ojalá, como si) that have nothing to do with si.

Quick shortcut: same triggers as the present subjunctive, but with a past or conditional main verb, the que clause takes the imperfect subjunctive (Quería que vinieras). Three extra patterns use it too: quisiera (polite wants), ojalá + imperfect (wishes that feel unlikely) and como si (comparisons).

Same triggers, shifted into the past

The triggers from the influence, emotion, doubt and purpose / future time lessons carry over, and so does the logic of when they call for the subjunctive. (Time words like cuando still take the subjunctive only for something not yet real at that point, so a completed event told in the past, Cuando llegó, me llamó, stays indicative.) The tense is what changes: when the main verb is in the imperfect, preterite, pluperfect or conditional, the verb in the que clause normally moves from the present subjunctive to the imperfect subjunctive:

Mi madre me pidió que la ayudara. (My mother asked me to help her.) No creía que fuera tan difícil. (I didn't think it was that difficult.)

The que clause is usually simultaneous with, or later than, the main verb: Quería que vinieras means you were to come at the time of the wanting or afterwards. For something that happened before the main verb, Spanish needs the pluperfect subjunctive (pluscuamperfecto de subjuntivo), which gets its own lesson.

The conditional counts as a past trigger

A conditional main verb also calls for the imperfect subjunctive, even when the situation is happening now or in the future, not in the past:

• Me gustaría que vinieras mañana. (I'd like you to come tomorrow.)
• Sería mejor que te quedaras en casa. (It would be better if you stayed at home.)
• Nos encantaría que nos visitaras. (We'd love it if you visited us.)

So the real question isn't "is the situation in the past?" but "is the main verb a past tense or a conditional?". For how the different main-verb tenses line up with the subjunctive tenses across a whole sentence, see Sequence of tenses with the subjunctive. A main verb in the present perfect (Me ha pedido que venga) typically behaves like a present, and that is one of the cases that lesson sorts out.

Courtesy: quisiera and pudiera

A few verbs use the imperfect subjunctive on their own, with no que clause, to sound softer and more polite. The best-known is quisiera, a gentler quiero:

• Quisiera una mesa para dos. (I'd like a table for two.)
• Quisiera hablar con el director, por favor. (I'd like to speak to the manager, please.)

The same softening works with pudiera (for podría) in requests, mostly in formal or service language: ¿Pudiera decirme dónde está la estación? (Could you tell me where the station is?) In everyday speech podría is more usual, while quisiera is perfectly normal in any register. This is a small set of verbs, not a pattern you can apply to any verb to make it polite. These courtesy uses are usually in the -ra form (quisiera is far more common than quisiese).

A related formal touch is debiera (for debería), which softens advice rather than a request: Debiera descansar más. (You ought to rest more.)

Wishes with ojalá

Ojalá means "I hope / if only", and its verb tells you how likely the speaker thinks the wish is:

• Present subjunctive: a wish that still feels possible. Ojalá venga mañana. (I hope he comes tomorrow.)
• Imperfect subjunctive: a wish that feels unlikely or contrary to the facts. Ojalá viniera mañana. (If only he'd come tomorrow.) Ojalá tuviera más tiempo. (I wish I had more time.)

Ojalá can also be followed by the pluperfect subjunctive for wishes about the past (Ojalá hubiera venido), which is covered in its own lesson.

Comparisons with como si

After como si ("as if"), standard Spanish uses the imperfect subjunctive, even when the main verb is in the present:

• Habla como si fuera el jefe. (He talks as if he were the boss.)
• Me trata como si no me conociera. (She treats me as if she didn't know me.)

The imperfect subjunctive here signals that the comparison is imagined rather than real. For an imagined situation that is earlier than the main verb, the pluperfect subjunctive is used (como si no hubiera pasado nada).

Common mistakes

• Quería que vinieras is the usual, traditional pairing for a past main verb. A present subjunctive (Quería que vengas mañana) is also heard, especially when the wish is still current or the event still lies ahead, but the imperfect subjunctive is the safe, standard choice, and the sequence-of-tenses lesson sorts out the flexible cases.
• ❌ Me gustaría que vienes. → ✅ Me gustaría que vinieras. (me gustaría is a trigger, so the que clause needs the subjunctive, and the conditional calls for the imperfect.)
• ❌ Habla como si es el jefe. → ✅ Habla como si fuera el jefe. (como si takes the subjunctive, not the indicative.)
• ❌ Ojalá tengo más tiempo. → ✅ Ojalá tuviera más tiempo. (or ✅ Ojalá tenga más tiempo, if the wish feels realistic; either way ojalá never takes the indicative.)

Quick check

1. Complete: Mis padres querían que yo __________ (estudiar) medicina.
2. Complete: Nos gustaría que __________ (venir, vosotros) a cenar.
3. Complete: Habla español como si __________ (ser) nativo.
4. Which sounds more hopeful, Ojalá apruebe el examen or Ojalá aprobara el examen?
5. Use the polite form of querer to say: "I'd like a coffee, please."

Key takeaways

• Subjunctive triggers stay the same; with a past or conditional main verb, the que clause takes the imperfect subjunctive (Quería que vinieras, Me gustaría que vinieras).
• The imperfect subjunctive covers what is simultaneous with or later than the main verb. Something earlier needs the pluperfect subjunctive.
• Quisiera (and, more formally, pudiera in requests) are set courtesy forms, not a pattern for every verb; debiera is a formal way to soften advice.
• Ojalá + present subjunctive = a realistic wish; ojalá + imperfect subjunctive = an unlikely or contrary-to-fact one.
• Como si takes the imperfect subjunctive, even after a present-tense main verb.
