Stem-changing Verbs in Spanish Past Progressive Tense

Stem-changing verbs in the Spanish Past Progressive Tense may undergo vowel changes when forming the gerund to express ongoing past actions. These changes occur in the stem of the verb before adding the -ando or -iendo ending.

It’s important to note that not all stem-changing verbs in other tenses change in the gerund form. The most common stem changes in gerunds are e>i and o>u, primarily in -ir verbs.
