Sequence of Tenses (Past)

Level 5

Choose the subordinate mood first, then express whether its event is simultaneous with, before or after the relevant reference point.

How It Works

Start With Meaning and Mood
A past main verb does not automatically trigger subjunctive: Sabía que estaba aquí asserts what was known, whereas Dudaba que estuviera aquí expresses doubt. Once the construction calls for subjunctive, relate the subordinate event to the chosen reference point.

A Past Viewpoint

  • For a simultaneous or later situation, imperfect subjunctive is common: Esperaba que vinieras (“I hoped you would come”). The -se form vinieses is also possible.
  • For an anterior situation, pluperfect subjunctive is common: Dudaba que hubieran terminado (“I doubted they had finished”). Hubiesen terminado is also possible. Doubting the event does not assert that it actually occurred.
  • In a report, conditional can express a later event from the past viewpoint: Prometió que llamaría (“He promised he would call”). A past form of ir a can also retain its structure: Dijo que iba a llamar.

Backshift Is Not Mechanical
Dijo que vendrá can retain a future viewed from the current speaking time. Likewise, a present subjunctive after a past main verb can retain current or future reference; its distribution also varies regionally. Compare the usual past viewpoint Le pedí que viniera with a context in which Le pedí que venga mañana still concerns tomorrow.

Keep the Reference Point Clear
Fue una lástima que no hubieran podido venir views their inability as anterior to a past point. Fue una lástima que no hayan podido venir can connect the event to the present evaluation or time frame. Neither tense should be labeled wrong merely because the main verb is past. Choose forms that convey the intended time relation and variety.

Examples (6)

  1. El profesor pidió que hiciéramos la tarea.

    The teacher asked that we do the homework.

    Word by Word: The teacher asked that we-did (subjunctive) the homework.

    The request expressed by pidió selects subjunctive; hiciéramos presents the requested homework as subsequent to that past request.

  2. Dudaba que hubieran terminado el proyecto.

    I doubted that they had finished the project.

    Word by Word: I-doubted that they-had (subjunctive) finished the project.

    Hubieran terminado places the possible finishing before the past doubt. The sentence does not assert that they actually finished.

  3. Me prometió que me llamaría.

    He promised me that he would call me.

    Word by Word: To-me he-promised that me he-would-call.

    Llamaría reports the promised call as later than the past promise. This is the past viewpoint; a current future viewpoint could use another form in a suitable context.

  4. Era importante que todos estuvieran presentes.

    It was important that everyone be present.

    Word by Word: It-was important that everyone were (subjunctive) present.

    The evaluation of importance selects subjunctive, and estuvieran presents the state as simultaneous with the past evaluation.

  5. Me sorprendió que no me hubieras dicho nada.

    It surprised me that you hadn't told me anything.

    Word by Word: To-me it-surprised that not me you-had (subjunctive) told anything.

    The surprise ('sorprendió') happened in the past. The action of not telling happened before the surprise, hence the pluperfect subjunctive 'hubieras dicho'.

  6. Pensábamos que el viaje sería más corto.

    We thought the trip would be shorter.

    Word by Word: We-thought that the trip would-be more short.

    The verb of thinking 'pensábamos' is in the past. The state of the trip being shorter is a future idea from that past perspective, so the conditional 'sería' is used.

Common Mistakes

  • Intended viewpoint: a request and cleaning situation viewed within a past time frame.

    Mi madre quería que yo limpie mi cuarto.
    Mi madre quería que yo limpiara mi cuarto.

    Limpiara gives the usual past viewpoint. Present limpie can be grammatical with current or future reference in suitable contexts or varieties; it is not universally wrong after quería. This card practices the past viewpoint.

  • Intended viewpoint: the visit is later than a past statement, without asserting that it is still future now.

    Ella dijo que vendrá a la fiesta.
    Ella dijo que vendría a la fiesta.

    Vendría places the visit after the past statement. Vendrá is also grammatical when the speaker retains a future reference from now. The difference is viewpoint, not an automatic ban on future after dijo.

  • Intended viewpoint: the inability to come is anterior to a past reference point.

    Fue una lástima que no hayan podido venir.
    Fue una lástima que no hubieran podido venir.

    Hubieran podido expresses anteriority from that past point. Hayan podido can instead retain a connection to the present. Both forms can be grammatical; choose the one that conveys the intended temporal relation.

Sequence of Tenses (Past)Level 5

Learn This First

To learn the past sequence of tenses, you must first understand the general logic of how main clauses trigger the subjunctive (Sequence of Tenses - Present). You also need to be proficient in the forms of the imperfect subjunctive and the concept of past-within-past actions (pluperfect) to correctly conjugate the subordinate verb.
