What Stem-Changing Verbs Are

Stem-changing verbs are verbs whose main vowel changes in some conjugated forms. For example, pensar becomes pienso and dormir becomes duerme, even though the infinitive stays the same.

These verbs matter because they are extremely common in everyday Spanish. The fastest way to learn them is to connect each infinitive to its stem-change pattern and a short example you can actually remember.
