What are Stem Changing Verbs?
Stem changing verbs are verbs that experience a change in their stem vowel when conjugated. In Spanish, the stem of a verb is the part of the verb that remains once the infinitive ending (-ar, -er, or -ir) is removed. These changes typically occur in the present tense, preterite tense, and subjunctive mood.
There are three main categories of stem changes based on the type of vowel that changes:
- e → ie: For example, "pensar" (to think) changes to "pienso" (I think).
- e → i: For example, "pedir" (to request) changes to "pido" (I request).
- o → ue: For example, "dormir" (to sleep) changes to "duermo" (I sleep).
Additionally, there's a fourth category for a few irregular verbs:
- u → ue: For example, "jugar" (to play) changes to "juego" (I play).
Conjugation Patterns
Understanding the conjugation patterns of stem changing verbs is essential for proper use. The changes occur in the present tense for all singular forms and for the third person plural (ustedes). Here’s a breakdown of how each type of stem-changing verb is conjugated.
1. e → ie Verbs
For verbs that change from e to ie, the stem change occurs in all forms except for the nosotros and vosotros forms. Here’s how "pensar" is conjugated:
- Yo pienso
- Tú piensas
- Él/Ella/Usted piensa
- Nosotros/Nosotras pensamos
- Vosotros/Vosotras pensáis
- Ellos/Ellas/Ustedes piensan
2. e → i Verbs
For verbs that change from e to i, the same rule applies. The stem change occurs in all forms except for the nosotros and vosotros forms. For example, "pedir" is conjugated as follows:
- Yo pido
- Tú pides
- Él/Ella/Usted pide
- Nosotros/Nosotras pedimos
- Vosotros/Vosotras pedís
- Ellos/Ellas/Ustedes piden
3. o → ue Verbs
For the o to ue stem changing verbs, the same pattern holds. Using "dormir" as an example:
- Yo duermo
- Tú duermes
- Él/Ella/Usted duerme
- Nosotros/Nosotras dormimos
- Vosotros/Vosotras dormís
- Ellos/Ellas/Ustedes duermen
4. u → ue Verbs
This category is less common, but "jugar" is a prime example:
- Yo juego
- Tú juegas
- Él/Ella/Usted juega
- Nosotros/Nosotras jugamos
- Vosotros/Vosotras jugáis
- Ellos/Ellas/Ustedes juegan
