Conjugation of verbs in Imperfect Subjunctive

In order to conjugate verbs in Imperfect Subjunctive, we need to previously master another tense: the Preterite.

The reason is, the whole conjugation of a verb in Imperfect Subjunctive is based on its “ellos” form in Preterite.

Here’s the formula we need to apply:

Formula to conjugate verbs in Imperfect Subjunctive

  1. Take the “ellos” form in Preterite Tense.
  2. Remove the “-ron” at the end.
  3. Attach the proper ending (choosing freely between 2 sets of endings)

The following table shows the 2 sets of endings we can choose from:

Subject PronounEndings with "-ra"Endings with "-se"


Let’s conjugate a couple of verbs applying the formula we just learned:

Verb “amar”

  1. In Preterite tense, the “ellos” form is “amaron”.
  2. We remove the final “-ron”  → “ama-“
  3. Finally, here is the full conjugation in Imperfect Subjunctive, with both sets of possible endings:
 Conjugation of "amar" with -raConjugation of "amar" with -se

Verb “ir”

  1. In Preterite tense, the “ellos” form is “fueron”.
  2. We remove the final “-ron”  → “fue-“
  3. Finally, here is the full conjugation in Imperfect Subjunctive, with both sets of possible endings:
 Conjugation of "ir" with -raConjugation of "ir" with -se

Uses of the Imperfect Subjunctive

We use the Imperfect Subjunctive in some sentences that express an unlikely possibility, or subjectivity about a past action: doubt, emotion…

Most times the Imperfect Subjunctive appears in dependent clauses after a relative pronoun, usually “que”.

Here are the most frequent types of sentences where we use the Imperfect Subjunctive:

1) After verbs that express a wish or preference (“querer, esperar, necesitar, desear, preferir, tener ganas de…”), when they are in any Past or Conditional tense, and followed by the word “que…”, then the next verb in the sentence is in Imperfect Subjunctive.

Queríamos que estudiaras más.
We wanted you to study more.

Esperaba que Ana viniese a mi cumpleaños.
I hoped Ana would come to my birthday.

Ellos preferirían que yo no dijera nada.

2) After “ojalá” or “ojalá que”, when they express a wish that seems unlikely to be fulfilled.

Ojalá ganásemos el partido.
I wish we would win the match. (unlikely)

3) After verbs that express a feeling or personal taste (“gustar, interesar, sorprender, preocupar, molestar, dar miedo…”) when they are in any Past or Conditional Tense and followed by the word “que…”, then the next verb is in Imperfect Subjunctive.

I wouldn’t like you to say that.

Nos daba miedo que nos atacasen.
We were scared that they would attack us.

4) After these phrases to speculate: “posiblemente, probablemente, tal vez, quizás, puede que, es posible que, es probable que”, the next verb is in Imperfect Subjunctive when the speculation is about the past.

Quizás tuvieran algún problema.
They might have had a problem.

Es posible que Juan y Pablo nos llamasen.
It’s possible that Juan and Pablo called us.

5) After these expressions that express disbelief or doubt: “no creer que, no pensar que, dudar que”, when those doubts are about past events.

El director no cree que eso fuera tan importante.
The director doesn’t think that was so important.

Dudo que comprasen el coche.
I doubt they bought the car.

6) After expressions that assess something, using this structure: ser + adjective + que… when the verb “ser” is in any Past or Conditional tense.

Sería bueno que vosotros dijerais la verdad.
It would be good for you guys to tell the truth.

Era importante que supiésemos la verdad.
It was important for us to know the truth.

7) After verbs in that express a plea, an order or an advice (“pedir, rogar, ordenar, aconsejar, prohibir…”) when they are in any Past or Conditional tense, and followed by the word “que…”.

Te aconsejé que lo investigaras.
I advised you to investigate it.
