Irregular past participles (hecho, dicho, visto)

While most past participles end in -ado or -ido, some of the most common verbs in Spanish have irregular past participles.

Common irregular past participles

Here are the irregular forms you will use most often:

escribir (to write)escritowritten

Using them with "haber"

You will frequently use these irregular forms with the helping verb haber (to have). When a past participle is used with haber, its ending is locked to -o; it does not change to match gender or number.

Who has made this mess?
¿Quién ha hecho este desorden?
I am very clumsy and I have broken the glass.
Soy muy torpe y he roto el vaso.
I have seen that you have spilled the juice.
He visto que has derramado el jugo.

Using them as adjectives

Just like regular past participles, these irregular forms can also be used as adjectives to describe the current state of a noun. When used this way, they must change their endings (-o, -a, -os, -as) to match the noun they describe.

The window is open and the glass is broken.
La ventana está abierta y el cristal está roto.

Notice how abierta ends in -a to match the feminine noun la ventana, while roto ends in -o to match the masculine noun el cristal.

I have picked up a piece of the broken mirror.
He recogido un pedazo del espejo roto.
