Stem-changing verbs: e to i (pido, sirves, repito)

A new stem change: e → i

You already know verbs whose stem vowel changes when it is stressed: querer gives quiero, poder gives puedo. A small group of -ir verbs changes the e to i instead. The three you know are pedir (to ask for, to order), servir (to serve) and repetir (to repeat).

I always order a black coffee.
Siempre pido un café solo.
The waiter serves the wine.
El camarero sirve el vino.
I repeat the word.
Repito la palabra.

I serve the soup and you serve the fish.
Yo sirvo la sopa y tú sirves el pescado.
The students repeat the words.
Los estudiantes repiten las palabras.

Nosotros and vosotros keep the e

The change only happens where the stress falls on the stem. In pedimos and pedís the stress moves to the ending, so the e stays — exactly as in queremos and podéis.

We ask for the bill.
Pedimos la cuenta.
What are you guys ordering?
¿Qué pedís vosotros?
We repeat the exercise.
Repetimos el ejercicio.

pedir or preguntar?

English says ask for both; Spanish does not. Pedir is to ask for something — a coffee, the bill, money. Preguntar is to ask a question.

I ask the time and order a coffee.
Pregunto la hora y pido un café.

With object pronouns

The pronouns go in front of the conjugated verb as usual, and le still becomes se before lo or la.

The children always ask me for money.
Los niños siempre me piden dinero.
The boy asks for water and his mother serves it to him.
El niño pide agua y su madre se la sirve.

Common mistakes

  • pidimos, repitís → pedimos, repetís: no change in the nosotros and vosotros forms.
  • repeto, servo → repito, sirvo.
  • decir follows the same pattern (dices, dice, dicen, but decimos) with its own yo form, digo.
