Presentation on theme: "Stem-Changing Verbs. The stem is what you have after you drop off the –ar, -er, or –ir: hablar mirar comer vender vivir abrir habl- mir- com- vend- viv-"— Presentation transcript:
The stem is what you have after you drop off the –ar, -er, or –ir: hablar mirar comer vender vivir abrir habl- mir- com- vend- viv- abr- So “stem-changing” means that the last vowel in the stem changes. The endings (-o, -as, -a, etc.) aren’t affected.
Let’s look at a regular verb: vender (to sell) vendo vendemos vendes vendéis vende venden Now let’s look at a stem-changing verb: querer (to want) quieroqueremos quieresqueréis quierequieren “Stem-changing” means that the last vowel in the stem changes. In this case, it’s an “e,” and it changes to an “ie” BUT NOT IN THE NOSOTROS AND VOSOTROS FORMS.
There are three types of stem-changing verbs: e ie e io ue querer (to want) pedir (to ask for) volver (to return) quiero queremospidopedimosvuelvo volvemos quieres queréispides pedísvuelves volvéis quiere quierenpide piden vuelve vuelven Notice that they all change in the same places: every person EXCEPT nosotros and vosotros.
Here are some common stem-changing verbs: e ie e i o ue querer (to want) pedir (to ask for) volver (to return) cerrar (to close) servir (to serve) poder (can) perder (to lose) repetir (to repeat) dormir (to sleep) pensar (to think) reír (to laugh) morir (to die) sentir (to feel) decir (to say, tell) contar (to count) comenzar (to begin)almorzar (to entender (to understand) have lunch) Sometimes you have more than one “e” or “o” in the stem. Remember that it’s the last vowel in the stem that changes.
“Cerrar” (to close) is a stem-changing verb. “Cenar” (to have dinner), which looks very much like “cerrar,” is not: cerrarcenar cierrocerramosceno cenamos cierrascerráiscenascenáis cierracierrancenacenan How do you know that “cerrar” is a stem-changing verb and that “cenar” isn’t? You can’t tell by looking at a verb if it’s going to stem change or not. You just have to memorize the ones that do.
