Stem -Changing Verbs — E to I (IR Verbs)

Stem -Changing Verbs — E to I (IR Verbs)

A special group of verbs of the third conjugation change the vowel e of the stem to i in the present tense, whenever the stress or accent falls upon this vowel. The verb pedir is typical of this group.

Present

pedir (to to ask for)

Past

pedir (to to ask for)

Note that as in the case of all vowel changing verbs, the first person plural remains regular since the accent does not fall upon the vowel of the stem but, instead, upon the first syllable of the ending.

These third conjugation verbs are conjugated exactly like pedir and thus change the vowel of their stem from e to i.

repetir	(to repeat)
servir	(to serve)
reírse	(to laugh)
vestirse	(to get dressed)
despedirse	(to say goodbye)
