Answer 2

Stem changers don't change in the nosotros or the vosotros form.

Some examples are:

dormir (o -> ue) duermo, duermes, duerme, dormimos, dormís, duermen

servir (e -> i) sirvo, sirves, sirve, servimos, servís, sirvieron

Answer 3

I think you mean the changes of:

---

o:ue, e:ie, e:i

yes, those would be stem changing verbs. - zinc55, Feb 1, 2010

The link above is good. Also note that these stem changes only occure in the present tense. It only happens when the syllable carries the stress and in the other tenses it does not carry the stress. There may be other changes in other tenses for other reasons but when we refer to "the stem changers" I think they all in the present tense.

Answer 5

Verbs like tener. The stem of tener is ten-, however the stem changes to

teng- in the yo form

tien- in the tu, usted, vosotros, and ustedes forms.

In other words, instead of taking off the -er ending and adding the appropriate suffixes, as you would do in a normal -er verb, there is some kind of change that is made to the verb stem before adding those endings.
