Remember that there are 3 kinds of stem-changing verbs:
1. e - ie stem-changing verbs
2. o - ue stem-changing verbs
3. e - i stem-changing verbs

In this lesson, we'll talk about the second kind of stem-changing verb, o - ue.  To conjugate these verbs, you start and end the same way you conjugate regular verbs. You simply add in one extra step.  After taking off the -ar,-er, or -ir ending, look for an o in the stem, and change it to ue.  Are you conjugating a verb in the nosotros or vosotros form?  Then don't do the extra step, and conjugate the verb just as you would a regular verb.

1. Take off the -ar, -er, -ir ending.
2. You're left with the stem. Change the o to ue
3. Add the conjugated ending.

Look at the example verb below, dormir.  The stem changes are in red, the unchanged parts of the verb stem are in blue, and the -ir verb endings are in green

There is one o-ue verb that is actually a u-ue verb: jugar.  See the conjugations of jugar, below.
jugar (play)
