Question

Conjugate the verb preferir.What takes place in the conjugation that makes this verb a stem-changing verb?

Answer 1

Preferir would be a e to ie stem changing verb, which means you would have to replace the e in the middle with ie, making it conjugate like this:

Yo - Prefiero

Tu - Prefieres

El/Ella/Usted - Prefiere

* Nosotros - Preferimos

* Vosotros - Preferís

Ellos/Ellas/Ustedes - Prefieren

Note that your wouldn't replace the e to ie for Nosotros and Vosotros for any stem changing verbs, just conjugate them as you normally would.
