Stem changing verbs
Stem changing verbs are named for what
they do– change in the stem.
You are going to make some alteration of
the stem before adding the verb endings.
You will use the present tense –ir endings
you already know (o, es, e, imos, en)
The hardest part of stem changers is
knowing which ones change and which
ones don’t.
Stem changers
There are 4 different ways a stem changing
verb can change (4 types).
You have already learned three types of
stem changing verbs: uue (jugar),
oue (like dormir), and eie (like
preferir).
Stem changers
The last category is a smaller category.
It is ei. Push link for a video on the four types of present tense stem changers.
servir = to serve is a stem changer.
It follows the same steps as the other stem
changing verbs that you have learned.
servir = to serve
First separate the stem from the infinitive
ending.
serv- is the stem.
Make the stem change ei
New stem sirvPut into box– remember it will look like a
boot… they are called boot verbs as well.
servir = to serve
sirvo
servimos
sirves
sirve
sirven
ei
There are some rules that can help you
distinguish between e i and e ie.
In order to be e i, the infinitive must end
in –ir. Now, that could be other categories
as well, but –ar and –er cannot be e i .
MR C VeSPeRS is also a way to help if you
are needing a pneumonic device.

MR. C VeSPeRS does not include all the
stem changers in this category. Other
infinitives are Sonreír (to smile) and freír
(to fry)….in this chapter.
Of the e to i stem-changing verbs that
appear in this chapter; pedir, servir, repetir,
and verstirse all following the given rules.
You must be careful on seguir as in the Yo
form you need to drop the –uir, not just the
–ir before adding your proper –ir present
tense endings.
Freír follows the given rules but you need to
keep the accent on all the “I”s.
Let’s practice seguir and freír.
seguir = to follow
First separate the stem from the infinitive
ending.
segu- is the stem.

Also remember that the YO form is irregular.

Stem Changers
I cannot give you a rule as to which verbs
stem change and which ones don’t. These
are just something that you have to learn as
you continue to use Spanish.
