Example

Zeichnung

No creo que pudiera trabajar en ningún otro sitio.

Es como si rejuveneciera cada vez que llega al trabajo.

Siempre quiso tener un taller de coches que fuera suyo.

¡Ojalá yo tuviera tan claro lo que quiero hacer!

Usage

We use the imperfect subjunctive in Spanish in the following cases:

  • the verb in a main clause is in a past tense or in the conditional simple,
    action in the subjunctive is taking place at the same time or later than the action in the main clause
    Example:
    Sin embargo, necesitaríamos algún voluntario que ayudase con la reparación.All the same, we would need a volunteer to help us with the repair job.
    Aunque no sabías que la ayuda fuera necesaria...Although you didn’t know that help was needed...
  • action in the main clause is in a present tense,
    action in the dependent clause took place earlier and no longer has any connection to the present
    Example:
    Creo que el dueño se alegra de que tú colaboraras.I think the owner will be glad that you helped.
  • particularly polite or cautious inquiries/statements, using verbs such as querer, poder, deber etc.
    Example:
    El conductor quisiera tener todo listo para esta tarde.The driver would like it if everything were finished by this evening.
  • after the expression como si with the meaning “as if/as … were”
    Example:
    Has trabajado como si fueras el jefe.You worked as if you were the boss.

How to conjugate the imperfect subjunctive in Spanish

To conjugate regular verbs in the imperfect subjunctive, we remove the infinitive endings (-ar, -er, -ir) and add the endings shown in the table below. For each person there are two possible conjugations (-ra or -se) and we use both interchangeably.

Person -ar
hablar		 -er
aprender		 -ir
vivir
yo hablara/
hablase		 aprendiera/
aprendiese		 viviera/
viviese
tú hablaras/
hablases		 aprendieras/
aprendieses		 vivieras/
vivieses
él, ella, usted hablara/
hablase		 aprendiera/
aprendiese		 viviera/
viviese
nosotros/-as habláramos/
hablásemos		 aprendiéramos/
aprendiésemos		 viviéramos/
viviésemos
vosotros/-as hablarais/
hablaseis		 aprendierais/
aprendieseis		 vivierais/
vivieseis
ellos/-as, ustedes hablaran/
hablasen		 aprendieran/
aprendiesen		 vivieran/
viviesen

Irregular conjugation

If the 3rd person plural is irregular in the preterite indicative, this irregularity remains unchanged in all forms of the imperfect subjunctive.

Example:
traer:bring ellos trajeron → yo trajera/trajese
ir:go ellos fueron → tú fueras/fueses
hacer:do/make ellos hicieron → él hiciera/hiciese
estar:be ellos estuvieron → nosotros estuviéramos/estuviésemos
tener:have ellos tuvieron → vosotros tuvierais/tuvieseis
saber:know (a fact) ellos supieron → ellos supieran/supiesen
andar:walk ellos anduvieron → ellos anduvieran/anduviesen
