Instruction: Past Perfect Subjunctive – Irregular

The pluperfect subjunctive tense in Spanish, or el pluscuamperfecto de subjuntivo, is used to describe actions that had been completed before another action in the past, often involving doubt, uncertainty, wishes, emotions, or hypotheticals. When dealing with irregular verbs, the structure of the tense remains the same, but the past participle used is irregular and must be memorized.

1. Forming the Pluperfect Subjunctive Tense

The pluperfect subjunctive tense is formed by combining the imperfect subjunctive form of the auxiliary verb haber with the irregular past participle of the main verb. As with regular verbs, haber can be conjugated using either the -ra or -se endings, though the -ra form is more commonly used in modern Spanish.

Haber Conjugation in the Pluperfect Subjunctive (Common -ra Form):

Yo

hubiera

(if) I had

Nosotros

*hubiéramos

(if) we had

(Juana, Juan)

hubieras

(if) you had

Vosotros

(informal Spain)

hubierais

(if) you all had

Él/Ella/Ud.

(Sra./Dr. García)

hubiera

(if) he/she/you had

Ellos/Ellas/Uds.

hubieran

(if) they/you all

*Notice that the "nosotros" form adds an accent to keep the proper stress.

Haber Conjugation in the Pluperfect Subjunctive (Less Common -se Form):

Yo

hubiese

(if) I had

Nosotros

*hubiésemos

(if) we had

(Juana, Juan)

hubieses

(if) you had

Vosotros

(informal Spain)

hubieseis

(if) you all had

Él/Ella/Ud.

(Sra./Dr. García)

hubiese

(if) he/she/you had

Ellos/Ellas/Uds.

hubiesen

(if) they/you all

*Notice that the "nosotros" form adds an accent to keep the proper stress.

2. Common Irregular Past Participles

Irregular past participles do not follow the standard -ado or -ido endings and must be memorized. These irregular forms are used across all perfect tenses, including the pluperfect subjunctive.

Examples of Common Irregular Past Participles:

  • Abrirabierto (opened)
  • Decirdicho (said)
  • Escribirescrito (written)
  • Hacerhecho (done, made)
  • Morirmuerto (died)
  • Ponerpuesto (put, placed)
  • Romperroto (broken)
  • Vervisto (seen)
  • Volvervuelto (returned)

3. Using the Pluperfect Subjunctive Tense with Irregular Verbs

The pluperfect subjunctive tense with irregular verbs is typically used in the subordinate clause of complex sentences (often following expressions that trigger the subjunctive mood). It describes actions that had occurred before another past action, especially in contexts involving doubt, emotions, or contrary-to-fact conditions.

    (I didn’t believe that you had done the homework so quickly.)

  • Si ella hubiera visto la señal, habría parado.
