1 Stem Changing verbs

2 Main Concept Each verb can be broken into two main parts.
The stem (everything but the ar, er, or ir.) The suffix (the ar, er, or ir.) Here are some examples. Verb Stem Suffix Hablar Habl Ar Comer Com Er Vivir Viv Ir Preguntar Pregunt ar

3 The Types There are four types of stem changing verbs.
e to ie stem changers. o to ue stem changers. u to ue stem changers. e to i stem changers. Ar, Er, and Ir can be any of the first three. Only Ir verbs can be e to i stem changers. NO VERB STEM CHANGES IN THE NOSOTROS FORMS: NO CHANGES IN “NO”SOTROS

4 Where the Change Takes Place
The change takes place in the penultimate (second to last) syllable of the infinitive. So if my verb is Repetir I break it into syllables Re/pe/tir The penultimate syllable is pe. (re/pe/tir) This is the syllable that will be changed.

5 The Change There is no good way of knowing which verbs stem change other than to memorize them. If the vowel in the penultimate syllable is an e we change it to ie most often (this is a very common stem change) e we change it to i in some verbs. o we change it to ue (also very common). u we change it to ue.

6 Process This is really EASY so watch carefully!
As long as the subject is not Nosotros,I take the penultimate syllable, Change the letter appropriately, Add the appropriate ending. ¡Fácil, no! Querer Quierer Yo Quiero

7 Steps: First, remove the last two letters (-ar, -er or –ir)
Second, replace the second to last syllable’s vowel with the appropriate letters. Third, place the correct endings on the end of the verb. REMEMBER – NOSOTROS DOES NOT CHANGE!!

8 Example Dormir (o-ue) Yo duermo Tu duermes El/ella/ud duerme
Nosotros dormimos Ellos/ellas/uds duermen ** note that the verb DOES NOT change in the nosotros form**
