Regular formation for -ER <strong>and</strong> -IR verbs: take off the infinitive ending, then add -ido:<br />

COMER-comido; VIVIR-vivido; BEBER-bebido; SALIR-salido<br />

<strong>The</strong>re are a number of verbs that have irregular past participles, <strong>and</strong> these must be memorized.<br />

abrir-abierto<br />

morir-muerto<br />

decir-dicho<br />

poner-puesto<br />

descubrir-descubierto resolver-resuelto<br />

escribir-escrito<br />

ver-visto<br />

hacer-hecho<br />

volver-vuelto<br />

Forms of the present perfect tense of the indicative mood.<br />

HABER + PAST PARTICIPLE<br />

he<br />

hablado<br />

has<br />

hecho<br />

ha<br />

comido<br />

hemos<br />

hablado<br />

habéis<br />

escrito<br />

han<br />

salido<br />

Examples. Hemos visto París. We have seen Paris.<br />

Ellas han escrito la carta. <strong>The</strong>y have written the letter.<br />

Te has levantado temprano hoy. You’ve gotten up early today.<br />

Note that the past participle form is invariable when it is part of a perfect tense: it does not<br />

“agree” <strong>with</strong> the subject in gender or number. (We do not say “Hemos vistos” or “Las muchachas<br />

han salidas;” these are incorrect. We say “Hemos visto,” <strong>and</strong> “Las muchachas han salido.”)<br />

Note also that object pronouns always precede forms of perfect tenses in Spanish. <strong>The</strong>y are never<br />

attached to the end of the past participle, nor can they be placed in between the past participle <strong>and</strong><br />

the form of haber.<br />

B. Subjunctive Mood of the Present Perfect Tense.<br />

Suppose we had a sentence like “I hope they have arrived.” <strong>The</strong> dependent noun clause “that<br />

they have arrived” contains a verb in the present perfect tense, “they have arrived.” <strong>The</strong>re is also<br />

a subjunctive trigger, “I hope,” along <strong>with</strong> a change of subject (I am doing the hoping, they are<br />

doing the arriving), so we have a classic situation where the subjunctive mood is called for in the<br />

dependent noun clause. We cannot use the indicative “ellas han llegado” in this situation, but<br />

rather must use the subjunctive form of the present perfect tense, hayan llegado.
