Verbs with Stem Change

Before we start seeing verbs that have stem change, let us talk about the verb stem first. A verb stem is a part of the verb where suffix can be attached. So, if I take “tener” as an example, since the ending is -ER, ten- should be the stem for “tener”.

Since we know what the stem is, now we talk about how they change. It is always a vowel that changes in a stem, and there are 3 types of verbs that have stem change.
