Stem-changing verbs

Stem-changing verbs

AKA Boot verbs

Today we will

• Review how to conjugate stem-changing verbs

• Show our knowledge by taking a timed practice

• Apply these verbs to lesson 4 vocabulary on pastimes/sports

Why are they called "Boot verbs"?

• All the subject pronouns get a change in the stem of the verb before conjugating the ending.

• When you circle all except the Nosotros form, the chart looks a little like a boot.

• We don't learn the vosotros (only used in parts of Spain)

Let's break them down

O > UE stem change

• the o in the stem changes to a ue for all forms *except* nosotros form

• For example: I sleep - yo duermo ≠ dormo

• We return - volvemos. Nothing changes in the stem for this form.

U > UE

• *jugar* to play, is a u->ue stem changing verb

• This is the only verb that makes this change

• it has its own stem-change

E > IE

• The verb querer (to want) has this change

• Quer - er (remove ending)

• Quie - (change stem)

• Conjugate ending (Yo quier-o)

• Not nosotros- queremos

E > IE

• We have already learned a verb that sort of follows this pattern

• The verb Tener follows this pattern except in the Nosotros AND yo formis

• This makes it a "sock verb" because it only changes where a "sock" would go inside a boot

E > I

• The verb repetir (to repeat) has this change

• Repet - ir (remove ending)

• Repit - (change stem)

• Conjugate ending (Yo repit-o)

• Not nosotros- repetimos

What if I forget?

Sometimes, when you do it 'wrong,' it feels wrong, like when you spell a word wrong and it just doesn't look 'right'. It will take time & practice. This is just the introduction.

Mistakes are VERY common when learning a new language and generally do not affect comprehension/understanding: people will still usually understand what you're saying

But keep practicing. You will see it like this (o:ue) in our vocab lists.
