LEARN SPANISH FUTURE PERFECT (Futuro Perfecto - Future Perfect) OF THE SUBJUNCTIVE MOOD

When we translate the tenses corresponding to the Spanish subjunctive mood into English we will do it according to the context. We always have to interpret the sentence and translate accordingly.

Before we study the future perfect of the subjunctive mood we need to learn some basic concepts about Spanish verbs. Spanish verbs are always either regular or irregular as it happens with English verbs. All Spanish verbs end either in "-ar", "-er" or "-ir". These are the three Spanish conjugations.

Example

Hablar (to speak) Correr (to run) Añadir (to add)

To form the future perfect of the subjunctive mood, we need to use the auxiliary verb "haber" (have) in its future simple of the subjunctive mood and the past participle of another verb. To form the past participle of the regular verbs in Spanish, we need to take the verb as we find it in the dictionary and remove the last two letters. Then, if the verb ends in "-ar" we will add the ending "-ado" and if the verb ends in "-er" or "-ir" we will add the ending "-ido".

Example

For the verbs ending in -ar:

yo (I) hubiere
tú (You) hubieres
él, ella, usted (he, she, you formal) hubiere
nosotros, nosotras (we) hubiéremos
vosotros, vosotras (you all) hubiereis
ellos, ellas, (they) ustedes (you all formal) hubieren

Example: We take the verb "hablar" (to speak). We remove the "-ar". We are left with "habl-" (the stem) and then we add "-ado". In this way we have the past participle of the verb "hablar" (to speak).

To conjugate the future perfect of the subjunctive mood of the verb "hablar" (to speak) we will use the future simple tense of the subjunctive mood of the verb "haber" (to have) and the past participle of the verb "hablar" (to speak).

hablar hablar--
yo (I) hubiere hablado (I had spoken)
tú (you) hubieres hablado (you had spoken)
él, ella, usted (he, she, you formal) hubiere hablado (he, she had spoken)
nosotros, nosotras (we) hubiéremos hablado (we had spoken)
vosotros, vosotras (you all) hubiereis hablado (you all had spoken)
ellos, ellas, (they) ustedes (you all formal) hubieren hablado (they had spoken)

For the verbs ending in -er:

yo (I) hubiere
tú (You) hubieres
él, ella, usted (he, she, you formal) hubiere
nosotros, nosotras (we) hubiéremos
vosotros, vosotras (you all) hubiereis
ellos, ellas, (they) ustedes (you all formal) hubieren

Example: We take the verb "correr" (to run). We remove the "-er": We are left with corr- (the stem) and then we add "-ido". In this way we have the past participle of the verb "correr" (to run).

To conjugate the future perfect of the subjunctive mood of the verb "correr" (to run) we will use the future simple tense of the subjunctive mood of the verb "haber" (to have) and the past participle of the verb "correr" (to run).

correr correr--
yo (I) hubiere corrido (I had run)
tú (you) hubieres corrido (you had run)
él, ella, usted (he, she, you formal) hubiere corrido (he, she had run)
nosotros, nosotras (we) hubiéremos corrido (we had run)
vosotros, vosotras (you all) hubiereis corrido (you all had run)
ellos, ellas, (they) ustedes (you all formal) hubieren corrido (they had run)

For the verbs ending in -ir:

yo (I) hubiere
tú (You) hubieres
él, ella, usted (he, she, you formal) hubiere
nosotros, nosotras (we) hubiéremos
vosotros, vosotras (you all) hubiereis
ellos, ellas, (they) ustedes (you all formal) hubieren

Example: We take the verb "añadir" (to add). We remove the "-ir": We are left with añad- (the stem) and then we add "-ido". In this way we have the past participle of the verb "añadir" (to add).

To conjugate the future perfect of the subjunctive mood of the verb "añadir" (to add) we will use the future simple tense of the subjunctive mood of the verb "haber" (to have) and the past participle of the verb "añadir" (to add).

añadir añadir--
yo (I) hubiere añadido (I had added)
tú (you) hubieres añadido (you had added)
él, ella, usted (he, she, you formal) hubiere añadido (he, she had added)
nosotros, nosotras (we) hubiéremos añadido (we had added)
vosotros, vosotras (you all) hubiereis añadido (you all had added)
ellos, ellas, (they) ustedes (you all formal) hubieren añadido (they had added)

The differences between the persons "tú" (you), "vosotros" (you all), "usted" (you formal) and "ustedes" (you all formal) are explained in Spanish Personal Pronouns .

Some of the irregular verbs will be conjugated exactly in the same form, adding the same sets of endings; the only difference is that they will have some spelling changes in the stem of the verb. ***Remember*** Spanish Irregular verbs can be highly irregular and the general rule is "The rules do not apply".

Decir To Say
Yo hubiere dicho I had said
Tú hubieres dicho you had said
Él hubiere dicho he had said
Nosotros hubiéremos dicho we had said
Vosotros hubiereis dicho you all had said
Ellos hubieren dicho they had said

SOME GENERAL USES

We have to highlight that this tense has fallen into disuse in the spoken language and it is only used in some idioms and some formal documents such juridical or administrative ones. It can be used to speak about completed actions in the future or in the past.

Example

Llámame cuando hubieres terminado el proyecto.
Call me when you have finished the project.

In spoken Spanish we would say:

Llámame cuando termines el proyecto.
Call me when you have finished the project.

Nowadays, in spoken Spanish, we have practically substitute the future perfect of the subjunctive mood for the "pretérito pluscuamperfecto" (past perfect) of the subjunctive mood and in some cases for the present tense of the subjunctive mood.

Example

Hubiera ido si hubiere terminado antes.
I would have gone if I had finished earlier.

The above example normally would be:

Hubiera ido si hubiera terminado antes.
I would have gone if I had finished earlier.

Avísame cuando hubieres visto el regalo que te gusta.
Tell me when you see the present that you like.
