Verb endings
• If a verb ends in – • if a verb ends in –
er, you add:
•o
• es
•e
• emos
• en
ir, you add:
•o
• es
•e
• imos
• en
• So, since “preferir” ends en “ir”
(preferir), which endings will we
add?
• The “ir” endings:
•o
• es
•e
• imos
• en
Preferir
prefer o
prefer emos
prefer es
prefer e
prefer en
Now, let’s add our stem change.
• Remember, only the e in the stem can
change.
• querer
• perder
• If there are two e’s in the stem, the
second one always changes.
• preferir
• empezar
Now let’s change the stems.
Remember, e can change to ie
only within the boot. This means
the nosotros form never
changes!
Preferir
prefier o
prefer imos
prefier es
prefier e
prefier en
The u→ue and o→ue verbs work the
same way.

• Jugar
• to play
• Dormir
• to sleep
• Soñar
• to dream
• Volver
• to return (to a place)
• Devolver
• to return (a thing)
First, find the o or u in the stem that is
going to change
• Poder
• Jugar
• Dormir
• Soñar
• Volver
• Devolver
Then, decide which verb endings you
will use.
• For jugar:

•a

• For poder:
•o
• es
•e
• emos
• en
