Preterite tense morphing verbsVOCES 1

Morphing verbs In the preterite tense, there are a group of irregular verbs that are referred to

as morphing verbs.

Morphing verbs are verbs that completely change their stem. There are 3 groups of morphing verbs: u- stems

i- stems

j- stems

Because morphing verbs are irregular, none of the conjugated forms have written accents.

All morphing verbs, no matter what kind of stem they have, use the same endings.
