How to use the imperfect subjunctive in Spanish?

By: Irati de Nicolás Saiz

The imperfect subjunctive in Spanish is used similarly to the present subjunctive (to express desire, doubt, opinions, etc.), but when we talk about past events. For example: Quería que vinieras conmigo al concierto meaning I wanted you to come with me to the concert. It is also used when we have a situation contrary to present facts, for example: Ojalá estuviera de vacaciones meaning I wish I were on vacation Did you know it can also be used to make polite requests? The imperfect subjunctive isn’t that imperfect after all!

The Spanish subjunctive has three past tenses: the imperfect, present perfect, and the past perfect. Let’s start with the imperfect subjunctive, how to form it, and how to use it. But, don’t forget to check out "How to use the present perfect and past perfect subjunctive in Spanish?" to learn about the other two past tenses of the subjunctive.

How to form the imperfect subjunctive in Spanish

The imperfect subjunctive is formed following a very simple rule.

  1. Take the third-person plural form (ellos, ellas, ustedes) of the preterite in the indicative:
    bailaron meaning they danced, comieron meaning they ate, vivieron meaning they lived

  2. Take off the ending ron:
    bailaron, comieron, vivieron

  3. And add the following endings:

    Example
    yo
    -ra
    bailara
    -ras
    bailaras
    él, ella, usted
    -ra
    bailara
    nosotros
    -ramos
    bailáramos
    vosotros*
    -rais
    bailarais
    ellos, ellas, ustedes
    -ran
    bailaran

How to use the imperfect subjunctive in Spanish

Recall that the subjunctive is mostly used in a subordinate clause of a two-part sentence:

main clausesubordinate clause
Me gustaría que llegaras más temprano mañana.
Translation: I would like that you arrive earlier tomorrow.

In order to know when to use the imperfect subjunctive, there are two key questions you should ask yourself:

  1. Does the main clause have a trigger for the subjunctive?

    • A verb that expresses desire, doubt, necessity, opinion, etc.

    • A conjunction like a menos que meaning unless, para que meaning so that, etc.

    • A Spanish adjective clause describing a noun in the main clause that is unknown or uncertain for the speaker, for example:

      Buscaba una persona que supiera de finanzas.
      Translation: I was looking for a person who would know about finances.
  2. Does this trigger refer to the past or to a situation contrary to the present?

If your answer to both questions is yes, then we need the imperfect subjunctive. Let’s get to it!

Actions in the past

We use the imperfect subjunctive when we talk about the past in the same contexts where we would use the present subjunctive: to express doubt, wishes, opinions, negation, with trigger conjunctions, etc. We express the past in the main clause using a verb in the preterite, imperfect, or pluperfect indicative.

For example:

Present:
indicativesubjunctive
Espero que mis amigos lleguen a la cena.
Translation: I hope that my friends come to the dinner party.
Past:
imperfect indicativeimperfect subjunctive
Esperaba que mis amigos llegaran a la cena.
Translation: I was hoping that my friends would come to the dinner party.

The phrase esperaba que is a trigger for the subjunctive since it expresses hope. But because the verb in the main clause is in the imperfect indicative then we must use the imperfect subjunctive in the subordinate clause.

The same is true if the verb in the main clause is in the preterite or the pluperfect:

imperfect indicativeimperfect subjunctivepluperfect
No creí que fueran a venir.
Translation: I didn’t think they were going to come.
El director te dejó ir a la excursión con tal de que sacaras buenas notas.
Translation: The principal allowed you to go on the field trip provided that you got good grades.
Les habíamos pedido que trajeran más agua.
Translation: We had asked them to bring more water.

Situations contrary to present reality

The imperfect subjunctive is used to express situations that are contrary to present reality. In this case, it will refer to present or future actions using the trigger ojalá meaning I wish, or a verb in the conditional simple tense in the main clause. Let’s break it down!

  • ‘Ojalá’ - impossible present or unlikely future

    In a previous post on the Spanish subjunctive, we discussed that we could use the subjunctive to express wishes using ojalá meaning I wish. We can use ojalá followed by the imperfect subjunctive when we express a wish in the present that is impossible, for example:

    Ojalá fuera verano.
    Translation: I wish it were summer.

    Or a wish in the future that is unlikely to happen:

    Ojalá nos ganáramos la lotería.
    Translation: I wish we could win the lottery.
  • Hypothetical present or future

    To talk about hypothetical situations we can use the conditional mood in the main clause. When we have an expression in the main clause that triggers the subjunctive with a verb in the conditional simple, then the verb in the subordinate clause must be in the imperfect subjunctive.

    conditional simpleimperfect subjunctive
    Nos gustaría que buscaras otro trabajo.
    Translation: We would like you to find another job.
    Preferiría que sacaras la basura lo antes posible.
    Translation: I would prefer that you took out the garbage as soon as possible.

  • 'Si' clauses

    Another very common use of the imperfect subjunctive is when it’s used together with the conditional simple in a si meaning if clause. These types of clauses are used to talk about implications of a condition in the following order:

    si clause

    imperfect subjunctive

    main clause

    conditional simple

    Si tuviera dinero, compraría una mansión.
    Translation: If I had money, I would buy a mansion.

    These sentences are used to talk about situations that are contrary to the present reality like the example above. They can also be used to express a remote condition that could theoretically be fulfilled:

    si clause (imperfect subjunctive)main clause (conditional simple)
    Si fueras más amable, no tendrías tantos problemas.
    Translation: If you were nicer, you wouldn’t have so many problems.

Polite requests

Finally, the imperfect subjunctive is used as an alternative to the present indicative or the conditional simple to make a polite request with verbs poder meaning to be able, querer meaning to want, and deber meaning should/ought. For example:

  • ¿Pudieras ayudarme con la tarea?
    Translation: Could you help me with the homework?
  • Quisiéramos una mesa cerca de la ventana.
    Translation: We would like a table close to the window.

To sum up

In this post we saw how to form the imperfect subjunctive and the main uses of this tense. The imperfect subjunctive is used:

  • In subordinate clauses when the main clause has an expression that triggers the subjunctive, and the verb refers to:

    • an action in the past

    • a situation contrary to present reality

  • Or in the main clause to express polite requests.

Here’s a chart to show the different tenses that can be paired up with the imperfect subjunctive.
