Conjugation in Imperfect Subjunctive

  1. Take the verb form for the person «ellos» in Preterite tense
  2. Remove the «-ron» at the end of that form.
  3. Add the proper ending.

Uses of the Imperfect Subjunctive

In general, the Subjunctive mode is used mostly in sentences that express subjectivity. The problem is, it is only in certain types of sentences that we use it, and because of that it is better to learn each individual case.

The most common cases for the Imperfect Subjunctive are:
