What Is The Stem of a Spanish Verb? The stem is the part of the verb form that contains the underlying meaning of the verb. To identify the stem, we simply remove the verb’s ending (-ar, -er, -ir) from its infinitive form.

The stem of a verb is what is left when you remove the infinitive ending (‐ar, ‐er, or ‐ir). Because the stem of the verb changes, these verbs are called stem‐changing verbs, or stem‐changers. You must learn each particular verb and remember that it is a stem‐changer.

It is impossible to identify that a verb is a stem‐changer simply by looking at the infinitive unless you have previously learned this particular verb and remember that it is a stem‐changer. Stem‐changing verbs could be – ar, –er, or – ir verbs.

Stem-Changing Verbs

• E changes to IE. QUERER – to want. yo. quiero. nosotros. queremos. tú quieres. vosotros. queréis. él. quiere.
• O changes to UE. PODER – can, to be able to. yo. puedo. nosotros. podemos. tú puedes. vosotros. podéis. él. puede.
• E changes to I. REPETIR – to repeat. yo. repito. nosotros. repetimos. tú repites. vosotros. repetís. él.

Stem-changing verbs could be – ar, –er, or – ir verbs.

Verbs with two different stems or radicals in the present tense may be called stem-changing verbs, shoe verbs, or boot verbs. The last two names come from the fact that a line drawn around the stem-changed, present tense conjugations (all forms except nosotros and vosotros) creates a shoe or boot.

What Are French Stem-changing Verbs? Stem-changing verbs are the group of -er verbs that have two different stems: 1. One stem for the first person singular (me), second person singular (informal you), third person singular (he, she, formal you) and third person plural (they) conjugations.

In this lesson, we have learned about some verbs that have e > ie and e > i stem changes in the present tense, such as pensar (to think), querer (to want/love), preferir (to prefer), empezar (to start/begin), perder (to lose), entender (to understand), comenzar (to start/begin), and cerrar (to close).
