Stem change (ie) help session

There are 2 parts to every verb, the stem and the ending.

• Ending: the -ar, -er, -ir at the end of the verb

• Stem: the part that is left after the ending is taken off

• Stem changers are verbs that have a spelling change in the stem (the part without the ending)

• For this lesson the verbs will have an "e" that changes to "ie"

• No, only specific verbs stem change. You will have to memorize the list.

• This is just a small list, there could be other verbs that also stem change.

​

• cerrar- to close

• confesar- to confess

• comenzar- to begin

• defender- to defend

• empezar- to begin

• entender- to understand

• mentir- to lie

​

• nevar- to snow

• pensar- to think, plan

• perder- to lose

• preferir- to prefer

• querer- to want

• recomendar- to recommend

• sentir- to feel, regret

• Take the "e" and change it to "ie" in all forms except nosotros.

  • Only change forms that fit inside the boot.

• Replace the -ar/-er/-ir with the appropriate ending.

• If the stem has more than one "e", you will change the 2nd "e".
