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.
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 |
Tú (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 |
Tú (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.
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.
