StemEnding

What is a “stem-change?” The verbs we have learned in the past are

“regular” verbs. Unfortunately, it can’t ALL be that easy! Some verbs have a stem that changes

along with the ending in some forms. Ex: Jugar Yo Juego

Basics Here are the basic stem-changing groups It will be the last vowel in the stem that changes Notice that all forms change, except in the nosotros

and vosotros forms.
