Verbos Irregulares - Co-construct
We are going to go through these irregular verbs and see if you can figure out the correct forms of the verbs.

These are all boot verbs/stem changing verbs, except for the last two on this page. This means that the verb conjugations are irregular in every form except for the "nosotros/as" form. This also means that the "stem" (the first vowel) changes. However, the endings are formed the same as any other present tense verb. Each verb shows, underneath, what the first vowel will change to in order to form the correct conjugations.
