Stem-Changing Verbs Yes, again!

El Presente In the present tense of stem-changing verbs we learned that there are 3 major changes that take place. O changes to UE E changes to IE E changes to I

REPASO: REVIEW When a verb has a stem-change, they take the normal present tense endings. -AR-ER-IR -o-o-o -as-es-es -a-e-e -amos-emos-imos -áis-éis-ís -an-en-en

LAS BUENAS NOTICIAS: The Good News There are NO new endings to memorize.

LAS MALAS NOTICIAS: The Bad News If you do not remember these verbs, you have more memorizing to do as well as a bit of a new twist to learn.

¡Estoy flipando, Sr. Mann! ¿Qué voy a hacer con estos verbos?

Do you remember…? SHOE VERBS?

EL PRESENTE All of these verbs are SHOE VERBS in the present tense. That means that ALL forms will make the change EXCEPT nosotros and vosotros.

contar - to count cuentocontamos cuentascontáis cuentacuentan

defender - to defend defiendodefendemos defiendesdefendéis defiendedefienden

servir - to serve sirvoservimos sirvesservís sirvesirven

Tengo una pregunta… Did you see how each verb follows the shoe pattern?

EL IMPERFECTO THERE IS NO SUCH THING AS A STEM-CHANGING VERB IN THE IMPERFECT TENSE. ALL VERBS ARE REGULAR!!!!! (except ir, ser, and ver)

contar - to count contabacontábamos contabascontabais contabacontaban

defender - to defend defendíadefendíamos defendíasdefendíais defendíadefendían

servir - to serve servíaservíamos servíasservíais servíaservían

EL PRETÉRITO This is where it starts to get a little complicated. Let’s look at the rules for stem- changing verbs in the preterite one at a time.

There ARE stem- changing verbs in the preterite.

They do NOT follow the same rules or patterns as the present tense.

-AR VERBS Make NO changes in the preterite at all!! Treat them just like any other regular verb.

contar - to count contécontamos contaste contasteis contócontaron

-ER VERBS Make NO changes in the preterite either!!!! Treat them just like any other regular verb.

defender - to defend defendídefendimos defendistedefendisteis defendiódefendieron

-IR VERBS oThese DO change in the preterite. oBut, they are no longer SHOE verbs. oThey become SANDAL verbs. oThat means that ONLY the 3rd person singular and plural changes. oThere are only TWO changes:

O to U and E to I are the only changes that occur.

servir - to serve servíservimos servisteservisteis sirviósirvieron

HUH?

Wanna run that by me again? oOnly -ir verbs stem-change. oThe only changes are O to U and E to I. oThe change only takes place in the BOTTOM forms on the chart.

Let’s look at a few verbs to see how this works… odormir (ue, u) ohervir (ie, i) opedir (i, i) oThe first note is the present tense change. oThe second note is the preterite tense change.

dormir - to sleep oPresent - changes o to ue. oImperfect - NO CHANGE oPreterite - changes o to u. oLet’s look!
