Question

Selecciona todos los verbos que son irregulares en pretérito perfecto.

Answer 1

Answer:

Algunos verbos que son irregulares en tiempo pretérito perfecto son:

1. Saber.
2. Tener.

Explanation:

There some verbs that, when are conjugated in Perfect Preterite, their endings actually change regarding their infinitive form, I mean, the verbs in infinitive form finish in "ar," "er" or "ir," a person could think that a verb finished in those letters, in its preterite perfect form (which finishes in "ado" or "ido"), just need to remove the ending and adding "ado" or "ido" as the example:

• Viajar: (remove the ending) viaj: (add the ending for perfect preterite ado) viajado.
• Vivir: (remove the ending) viv: (add the ending for perfect preterite ido) vivido.

When the verbs don't finish in "ar" or "ir" but in "er," the form that applies for the is the ending "ido," by this reason is named irregular, because the verbs finishes in a form different from the infinitive form, how the verbs selected in the answer:

1. Saber: (remove the ending) sab: (add the ending "ido" because the verb finishes in "er") sabido.
2. Tener: (remove the ending) ten: (add the ending "ido" because the verb finishes in "er") tenido.

Answer 2

They're saber, tener and vivir. ER and IR verbs are irregular verbs.
