This video was for a group presentation at their request. Maybe you can still find it helpful? I tried to have fun while making it because life’s too short!
This video lesson covers -ir verbs in the preterite that stem change.
In the present, they change (o-ue) in the yo, tú, él/ella/ud, ellos/ellas/uds forms. In the preterite, they do something a little different. I apologize for it being a little long. Hope this video is helpful.
Let me know if you have any questions, comments or suggestions about this video below. Enjoy!
