The present perfect subjunctive is formed using the formula below:

present subjunctive conjugation of haber + the past participle = present perfect subjunctive

The box on the right shows the present subjunctive conjugation of the helping verb haber. The past participle of hablar (to speak) is hablado.

Below are examples of the present perfect subjunctive. Note that there are two possible English translations for each example.

haya hablado - I spoke (or) I have spoken

hayas hablado - you spoke (or) you have spoken

hayamos hablado - we spoke (or) we have spoken

The present perfect subjunctive is used in the same types of clauses as the present subjunctive, and normally is used: to indicate the action as completed with governing verbs in the present or future tense or command forms. Let's look at some example sentences with other regular verbs:

Tal vez te hayas equivocado.
Perhaps you have made a mistake.

Cuando la guerra haya terminado todo estará destruido.
When the war has ended everyting will be detroyed.
