Understand and use o>ue, e>ie, and e>i stem-changing verbs
Gramática: Verbos con cambio de raíz (Stem-changing verbs)
We’ve seen a number of verbs so far that change the final vowel of their stem in some of their conjugated forms, for example: ¡Ay! Me duelen los pies (doler), and Los niños tienen diez años (tener). These are not random irregularities– there are three categories of stem-changing verbs, which all follow a similar pattern of changing the last vowel of their stem in the conjugated forms where that vowel is stressed.
A. Verbos con cambio de raíz e>ie
Comenzar (to start, to begin) | ||
Singular | Plural | |
1a | comienzo | comenzamos |
2a | comienzas | comenzáis |
3a | comienza | comienzan |
Note that the nosotros and vosotros forms do not change their ‘e’ to ‘ie’, because the stress in those forms falls on the next syllable.
And remember that the stem-changing vowel does not affect the personal ending for the verb, which depends on who the subject is and whether the verb is in the -AR, -ER, or -IR conjugation group. Here’s an example of an -ER verb that has the e>ie stem change:
Querer (to want) | ||
Singular | Plural | |
1a | quiero | queremos |
2a | quieres | queréis |
3a | quiere | quieren |
B. Verbos con cambio de raíz o>ue
Dormir (to sleep) | ||
Singular | Plural | |
1a | duermo | dormimos |
2a | duermes | dormís |
3a | duerme | duermen |
C. Verbos con cambio de raíz e>i
Interestingly, all the verbs in this group are -IR verbs.
Pedir (to ask for, to request) | ||
Singular | Plural | |
1a | pido | pedimos |
2a | pides | pedís |
3a | pide | piden |
