  • 1. Stem-Changing –AR Verbs Let’s give them the boot!
  • 2. We already know our subject pronouns … nosotrosyo nosotras vosotrostú vosotrasél ellosella ellasUd. Uds.
  • 3. … and we already know our –AR verb endings …-o -amos-as -áis-a -an
  • 4. So what else do we need to knowabout 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.
  • 5. The Three Rules1. 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.
  • 6. 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.
  • 7. contar (ue): to count, to tell• yocuento • nosotros/as contamos• túcuentas • vosotros/as contáis• élcuenta • elloscuentan• ellacuenta • ellascuentan• Ud. cuenta • Uds. cuentan
  • 8. So, what does this have to do with a boot?• yocuento • nosotros/as contamos• túcuentas • vosotros/as contáis• élcuenta • elloscuentan• ellacuenta • ellascuentan• Ud. cuenta • Uds. cuentan
  • 9. First, let’s X out the forms that don’t have a stem change.• yocuento X • nosotros/as contamos• túcuentas X • vosotros/as contáis• élcuenta • elloscuentan• ellacuenta • ellascuentan• Ud. cuenta • Uds. cuentan
  • 10. Then, let’s “circle” the forms that do have a stem change.• yocuento X • nosotros/as contamos• túcuentas X • vosotros/as contáis• élcuenta • elloscuentan• ellacuenta • ellascuentan• Ud. cuenta • Uds. cuentan
  • 11. Alright, it is not a perfect boot.• yocuento X • nosotros/as contamos• túcuentas X • vosotros/as contáis• élcuenta • elloscuentan• ellacuenta • ellascuentan• Ud. cuenta • Uds. cuentan

  • 13. Wait. Did you see that last verb? jugar (ue): to play It’s an irregular stem-changing verb, but it still honors the boot.• yojuego • nosotrosjugamos• tújuegas • vosotrosjugáis• éljuega • ellosjuegan
  • 14. 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.
  • 15. 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.
  • 16. If it’s in the boot, change the root! cerrar (ie): to close• yocierro X • nosotros/as cerramos• túcierras X • vosotros/as cerráis• élcierra • elloscierran• ellacierra • ellascierran• Ud. cierra • Uds. cierran
