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

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:

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).

For the verbs ending in -er:

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).

For the verbs ending in -ir:

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).

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 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.
