In addition to the present subjunctive and imperfect subjunctive, we can also form other conjugations in the
subjunctive mood. Following are some more subjunctive possibilities.
Present Perfect Subjunctive
We can also form perfect tenses in the subjunctive.
To conjugate in the present perfect subjunctive, we simply conjugate haber
in the present tense subjunctive and combine it with a past participle.
+ past participle
Yo dudo que Carlos haya
hecho su tarea.
I doubt that Carlos has done
Me emociono que nosotros hayamos ganado el campeonato.
I'm trilled that we have won
Es impresionante que tú hayas
tomado tantos cursos.
It is impressive that you have taken
so many classes.
The Pluperfect Subjunctive
Note: There is an alternate set of imperfect
subjunctive endings which means that you could also see haber conjugated
as: hubiese, hubieses, hubiese, hubiésemos, hubieseis and hubiesen in the pluperfect subjunctive.
And to conjugate
in the pluperfect subjunctive, we conjugate haber in the imperfect
subjunctive and use it with a past participle.
+ past participle
familia esperaba que nosotros hubiéramos llegado
My family hoped that we had arrived
Me molestaba mucho que ella no hubiéra dejado
It bothered me a lot that she had not left
Él no creía que ellos hubiéran comprado
He didn't believe that they had bought
The Future Subjunctive
is (or more accurately "was") a future subjunctive. It is not used much
anymore and is mostly found in literature. The present subjunctive is now used
in its place. The future subjunctive is formed the same way as imperfect subjunctive
but with a different set of endings. Here are the future subjunctive endings,
and the verb "hablar" conjugated in future subjunctive:
future subjunctive endings:
difference between the future and the future subjunctive for some conjugations
is only an accent mark (or lack thereof).
