O to UE Stem-Changing Verbs

Here is a lesson that for some reason is more popular than some of my other You Tube posts. It goes over some "stem-changing" verbs. There are some verbs that experience a change in the stem when you conjugate them. Remember, normally when you conjugate the verb, the stem stays the same, it's the ending that changes, but these verbs are exceptions to the rule. But when the verb is stem-changing, the Nosotros form will NOT experience the change.
