Many years ago, Endel Tulving, a phycologist, discovered something that can help you memorize the conjugation of Spanish irregular verbs.
Would you like to know what that is? I will tell you more about it later in the lesson. First, I would like to share with you what stem-changing verbs are and how you can conjugate them.
A Spanish irregular verb is a verb that suffers a change in its stem when it is conjugated.
A verb stem is the root of a verb. For example, in the verb amar, am is the stem, and ar is the ending.
In Spanish, all verbs end in one of three ways: -ar, -er, -ir. Eliminate the ending of a verb, and all you are left with is its stem.
In Spanish, a verb is considered irregular when there is a change in its stem when conjugated. If the stem of a verb does not change when the verb is conjugated, then, it is considered a regular verb.
Let’s practice a bit! What’s the stem of the verb querer (to love)? It’s quer. When conjugated, the verb querer changes to quiero (I love), for example. Is querer a regular or an irregular verb in Spanish? Yes, it’s irregular! Its stem changes, for the vowel i is added in quer.
Oh! The verbs we are about to study are also called “boot verbs.” Have you ever wondered why? It’s because when they are conjugated and placed in a conjugation table, the only verbs that suffer a stem change form a boot.
That kind of looks like a boot, doesn’t it?
Notice in the chart that the nosotros and vosotros forms are not affected by this stem change in the present tense. The vos form is not affected by this change either.
Remember Endel Tulving and his discovery? Well, he formed two groups of students and gave each group 100 cards with words printed on them.
He asked one group to memorize the cards. The other group was asked to organize the cards into categories. The results surprised Endel! When tested, both groups remembered the vocabulary with the same precision.
Yes, organizing stem-changing verbs into a few categories can help you remember their conjugation!
So, what do you think? Do you dare to try organizing some irregular verbs into a few categories?
