Stem Changing Verbs Spanish

What are the types of stem changing verbs?

Stem changing verbs: O:UE in spanish

Remember, there are three types of infinitives: -ar, -er, -ir. Infinitives are made up of two parts: the ending and the stem. 

hablar - habl (stem) + ar (ending)
comer - com (stem) + er (ending)
vivir -
viv (stem) + ir (ending)

With regular verbs, the stem stays the same, and the ending changes as they are conjugated.
