SPA112: Stem Change Verbs o-ue and e-i

STEM CHANGING VERBS Remember, there are three types of infinitives: -ar, -er, -ir. Infinitives are made up of two parts: the ending and the stem. You already know how to conjugate verbs in the present tense, so the actual conjugation is easy. With stem change verbs we are adding the step of making a small vowel spelling change in the stem in all forms of the conjugation except the nosotros and vosotros. In the present tense, there are three groups of stem-changing verbs: e-ie, o-ue, and e-i. When this happens you use the 2nd e for the stem change Therefore I recommend…is Recomiendo and NOT Riecomendo. Now let's do o-ue: It follows the same principle as e-ie...so if you can do them, you can do these! Verb: Poder(o-ue)- to be able, can yo: puedo tú: puedes él/ella: puede ud.: puede nosotros(as): podemos vosotros(as): podéis ellos/ellas: pueden uds.: pueden Here are some common o-ue stem change verbs: almorzar: to eat lunch morir: to die aprobar: to approve mostrar: to show colgar: to hang mover: to move (an object) contar: to count probar: to test, sample costar: to cost recordar: to remember devolver: to return (an object) volver: to return (from someplace) dormir: to sleep soñar (con): to dream about sonar: to ring, to sound encontrar: to find morder: to bite volar: to fly The last form of stem change verbs that we will study is the e-i form.
