This group of verbs
takes a bit of concentration. There are many irregular
forms dealing with the stem changers. These verbs have
a change of o to ue
in most present tense conjugation forms, some preterite
forms, and almost all present subjunctive forms. These
verbs will have to be studied in their conjugated forms
in other sections of this site. Don't abandon hope! Once
you understand the patterns, it's easy to get it down!
Most important of all is simply to learn to recognize
the stem-changers, and what kind of stem change occurs.
