Past subjunctive
Carry wishes and non-factual clauses into a past viewpoint.
Understand the choice
The imperfect subjunctive carries wishes, reactions, doubts, purposes, and non-factual descriptions into a past viewpoint. Its -ra series comes from the third-person plural preterite stem and works across all verb classes.
Core rule: Use the imperfect subjunctive after past triggers and in subordinate clauses presenting an action as pending or non-factual.
Notice it in context
Quería que vinieras antes de que empezara la reunión.
I wanted you to come before the meeting started.
Use the imperfect subjunctive after past triggers and in subordinate clauses presenting an action as pending or non-factual.
Me sorprendió que no lo supieras.
I was surprised that you did not know it.
Past emotion triggers supieras.
Buscábamos a alguien que tuviera experiencia.
We were looking for someone with experience.
The unknown person triggers tuviera.
What to remember
- Remove -ron from hablaron, tuvieron, or fueron and add -ra endings: hablara, tuviera, fuera.
- The alternative -se series—hablase, tuviese, fuese—is also correct, though regional and stylistic preferences vary.
Common trap: Do not use the present subjunctive under a past viewpoint when the subordinate action is simultaneous or later in that past frame: quería que vinieras, not quería que vengas.
