1 Stem-Changing verbs (verbos con cambios radicales)

2 What is a stem-changing verb? As the name implies, a stem-changing verb has a change in its stem As the name implies, a stem-changing verb has a change in its stem A verb has two parts, the stem and the ar/er/ir ending. Hablar Correr Escribir

3 Types of stem-changers There are 3.5 types of stem-changers in Spanish. They are: E  IE (the most common) O  UE (common) U  UE (“jugar” is the ONLY verb that does this) E  I (applies to –ir verbs ONLY)

4 WHERE in the stem does the change happen? The stem change will always happen in the first vowel back from the ending. (Most times it’s the only vowel in the stem.) PENSAR (to think, e  ie) PREFERIR (to prefer, e  ie) DORMIR (to sleep, o  ue) ENCONTRAR (to find, o  ue) SERVIR (to serve, e  i)

5 How are these verbs conjugated? Stem changers do not change in all forms, just four. Let’s see how this works…

6 PENSAR (to think / to plan, e  ie) PIENSOPENSAMOS PIENSASPENSÁIS PIENSAPIENSAN Stem changers are also called “shoe” or “boot” verbs… The changes all happen inside the form of a shoe or boot!

7 PREFERIR (to prefer, e  ie) PREFIEROPREFERIMOS PREFIERESPREFERÍS PREFIEREPREFIEREN

8 QUERER (to want, e  ie) QUIEROQUEREMOS QUIERESQUERÉIS QUIEREQUIEREN

9 Ejemplos: Pienso llevar unos pantalones cortos porque hace calor. Laura prefiere las camisetas más que las blusas. Laura y Andrés quieren comprar botas nuevas. What do you notice about the verb AFTER the conjugated stem- changer?

10 Traduce: I want to buy these shoes and those socks. We prefer to shop after school. He plans to wear a jacket and a scarf. You think that (que) shopping is boring. *to shop: ir de compras

11 PODER (to be able (“can”), o  ue) PUEDOPODEMOS PUEDESPODÉIS PUEDEPUEDEN

12 DORMIR (to sleep, o  ue) DUERMODORMIMOS DUERMESDORMÍS DUERMEDUERMEN

14 SERVIR (to serve, e  i) SIRVOSERVIMOS SIRVESSERVÍS SIRVESIRVEN

15 PEDIR (to ask for, e  i) PIDOPEDIMOS PIDESPEDÍS PIDEPIDEN

16 PRÁCTICA: if a verb is in the nosotros form, rewrite it using a stem changed form, and vice versa. 1.Mis hermanos y yo dormimos hasta las 11. 2.Yo puedo cantar y bailar. 3.La princesa prefiere comer fuera de la casa. 4.Mis amigos y yo pedimos los espaguetis en el restaurante italiano. 5.Los chicos juegan al fútbol en el parque.

17 PRÁCTICA: translate the following 1.They serve the best pizza. (SUPERLATIVE!!!!) 2.We can wear coats and scarves in January. 3.I ask for boots and shoes for Christmas (la navidad). 4.My sister sleeps more than I. 5.You play soccer after school.

18 Final notes… There’s no way of looking at a verb and knowing that it’s a stem changer. However, the more familiar you are with Spanish, the more you will be able to “feel” a stem changer. Some Spanish 2 students can already do this There’s no way of looking at a verb and knowing that it’s a stem changer. However, the more familiar you are with Spanish, the more you will be able to “feel” a stem changer. Some Spanish 2 students can already do this If a verb (of 2+ syllables) changes stem (e.g., TENER—to have), then all verbs which contain that verb will also change stem (e.g., MANTENER—to maintain, OBTENER— to get).
