14.5. Conjugation of Regular Verbs in Present Tense: Stem Changes in Regular Verbs

When learning Spanish, understanding verb conjugation is crucial for effective communication. One of the more complex aspects of Spanish verb conjugation is the concept of stem-changing verbs. These verbs, while regular in their endings, undergo changes in their stem when conjugated in certain forms. In this section, we will delve into the intricacies of stem-changing verbs in the present tense, providing you with the tools to master their usage.

Understanding Stem Changes

In Spanish, many verbs experience a change in their stem vowel when conjugated in the present tense. This change occurs in all forms except for the first and second person plural (nosotros/as and vosotros/as). The stem change is essential to maintain the phonetic consistency of the verb and can be categorized into three main types:

• e > ie: Verbs where the e in the stem changes to ie.
• o > ue: Verbs where the o in the stem changes to ue.
• e > i: Verbs where the e in the stem changes to i.

1. e > ie Stem-Changing Verbs

These verbs undergo a change from e to ie in the present tense. Let's take a look at the verb entender (to understand) as an example:

Subject Pronoun	Conjugation
yo	entiendo
tú	entiendes
él/ella/usted	entiende
nosotros/as	entendemos
vosotros/as	entendéis
ellos/ellas/ustedes	entienden

Notice how the stem entend- changes to entiend- in all forms except nosotros/as and vosotros/as.

2. o > ue Stem-Changing Verbs

In this category, the o in the stem changes to ue. Consider the verb poder (to be able to/can):

Subject Pronoun	Conjugation
yo	puedo
tú	puedes
él/ella/usted	puede
nosotros/as	podemos
vosotros/as	podéis
ellos/ellas/ustedes	pueden

Here, the stem pod- changes to pued- in all forms except nosotros/as and vosotros/as.

3. e > i Stem-Changing Verbs

The third type involves a change from e to i. Let's examine the verb pedir (to ask for/request):

Subject Pronoun	Conjugation
yo	pido
tú	pides
él/ella/usted	pide
nosotros/as	pedimos
vosotros/as	pedís
ellos/ellas/ustedes	piden

The stem ped- changes to pid-, except in the nosotros/as and vosotros/as forms.
