Stem-Changing –AR Verbs

Let’s give them the boot!

Page 2: Intro to  ar stem change verbs

We already know our subject pronouns …

yo nosotrosnosotras

tú vosotrosvosotras

Page 3: Intro to  ar stem change verbs

… and we already know our –AR verb endings …

-o -amos

-as -áis

-a -an

Page 4: Intro to  ar stem change verbs

So what else do we need to know about the present tense of –AR verbs?

• Some –AR verbs are regular stem-changing verbs. Sometimes they are called “boot” verbs. You will see why very soon.

• There are two categories of regular stem-changing –AR verbs, o to ue and e to ie.

• There are three rules that apply to these stem-changing verbs.

Page 5: Intro to  ar stem change verbs

The Three Rules

1. The stem change occurs in all forms except nosotros and vosotros.

2. The stem change occurs in the syllable directly before the verb ending.

3. The verbs have regular endings in the present tense.

Page 6: Intro to  ar stem change verbs

Let’s try one together.• We are going to start with an o to ue –AR verb,

contar (ue): to count, to tell.• Rule 1 says that the stem change will occur in

all forms except nosotros and vosotros, so we know that those will be contamos and contáis.

• Rule 2 says that the stem change will occur in the syllable directly before the verb ending, in this case it is the only o.

• Rule 3 says the endings will be regular.• Let’s put this together in a chart.

Page 7: Intro to  ar stem change verbs

contar (ue): to count, to tell

• yo cuento• tú cuentas• él cuenta• ella cuenta• Ud. cuenta

• nosotros/as contamos• vosotros/as contáis• ellos cuentan• ellas cuentan• Uds. cuentan

Page 8: Intro to  ar stem change verbs

So, what does this have to do with a boot?

• yo cuento• tú cuentas• él cuenta• ella cuenta• Ud. cuenta

• nosotros/as contamos• vosotros/as contáis• ellos cuentan• ellas cuentan• Uds. cuentan

Page 9: Intro to  ar stem change verbs

First, let’s X out the forms that don’t have a stem change.

• yo cuento• tú cuentas• él cuenta• ella cuenta• Ud. cuenta

• nosotros/as contamos• vosotros/as contáis• ellos cuentan• ellas cuentan• Uds. cuentan

• nosotros/as contamos• vosotros/as contáis• ellos cuentan• ellas cuentan• Uds. cuentan

Wait. Did you see that last verb? jugar (ue): to play

It’s an irregular stem-changing verb, but it still honors the boot.

• yo juego

• tú juegas

• él juega

• nosotros jugamos

• vosotros jugáis

• ellos juegan

Page 14: Intro to  ar stem change verbs

Take note!!!

• If it’s in the boot, change the root!• When stem-changing verbs are listed in a

glossary, they will indicate the change. (ue) indicates the stem change of o to ue.

Let’s try another one together.• We are going to try an e to ie –AR verb, cerrar

(ie): to close.• Rule 1 says that the stem change will occur in

all forms except nosotros and vosotros, so we know that those will be cerramos and cerráis.

• Rule 2 says that the stem change will occur in the syllable directly before the verb ending, in this case it is the only e.

• Rule 3 says the endings will be regular.• Let’s put this together in a chart.
