ANTE TODO • As you learned in Lección 6, –ar and –er stem-changing verbs in the present have no stem change in the preterite. • The –ir stem-changing verbs in the present however, do have a stem change. • Study the charts in the next slide and observe where the stem changes occur. These verbs are sometimes referred to as Slipper Verbs (preterite), as opposed to Boot Verbs (present). They take regular –ir preterite endings.
Stem-changing –ir verbs, in the preterite only, have a stem change in the third-person singular and plural forms. The stem change consists of either e to ior o to u, and occurs in the vowel closest to the ending. (preferir) (ei) pedir : pidió, pidieron (o u) morir (to die) : murió, murieron
Preferir: (e→ie present) (e→i preterite) BOOT SLIPPER PrefieroPreferimos Preferí Preferimos Prefieres Preferís Preferiste Preferisteis PrefierePrefierenPrefirióPrefirieron
Some common –ir stem changing verbs in the preterite are: (* means reflexive) (ei) (o u) • servir (to serve) dormir (to sleep) • pedir (to ask for, to order) dormirse (to fall sleep)* • repetir (to repeat) morir (to die) • seguir (to follow) morirse de hambre * (to die • conseguir (to get; obtain) of hunger, not literally) • preferir (to prefer) • sentirse (to feel) * • despedirse (to say goodbye) * • vestirse (to get dressed) *
When a verb is reflexive, you must include the reflexive pronoun before the conjugated verb. vestirse • me vestí nos vestimos • te vestiste os vestisteis • se vistió se vistieron
