How E to I Stem-changing Verbs Work

In short, e to i stem changing verbs work like this: in the yo, , él/ella/usted and ellos/ellas/ustedes forms, the “e” in the stem changes to an “i.”

This type of stem change only occurs with –ir verbs.

Let’s look at the present tense conjugation of pedir (to ask for, request, order), which is one of the most common e to i stem changing verbs in Spanish: 

yo pido
tú pides   
él/ella/ud. pide
nosotros pedimos
vosotros pedís
ellos/ellas/uds. piden

Notice that the nosotros and vosotros forms retain the original “e” of the stem, while the other stems change.

Here are some pedir stem changes in example sentences:
