Thurs. Apr 12 - 5B Present participles
You will be changing infinitives to their "ndo" form. Remember that ir verbs that have a stem change in the present tense, also have a stem change in the "ndo" form. In the "ndo" form these changes are e>i and o>u. The other irregular "ndo" forms are er and ir verbs whose stem ends in a vowel after the er or ir are removed.
