Pluperfect

Formation

The pluperfect (pluscuamperfecto) is formed with:

the auxiliary haber in the imperfect +  past participle of the verb

hablar  to speak
yo había hablado nosotros/as habíamos hablado
tú habías hablado  
él/ella/usted había hablado
ellos/as/ustedes habían hablado

Uses

In past narration, the pluperfect is used to express an action which precedes another past action or moment. In other words, the action in the pluperfect is prior to another past action or moment. In English, the pluperfect is formed using had + past participle.

Me dijeron que tenía que acabar high school y high school yo lo había acabado como hace dos años en Perú.
They told me that I had to finish high school and I had already finished high school about two years ago in Peru.

In affirmative sentences in Spanish, it is often, but not always, accompanied by the adverb ya (already).

Para las cinco ya había cenado y todo.
By five I had already had dinner and everything.

The pluperfect is also used in indirect speech in the past.

Me dijo que él nunca había conocido una mujer tan bonita como yo.
He told me that he had never met a woman as pretty as me.
