How do you recognize I verbs, J verbs, U verbs and UV verbs please?

Question

In lesson 2.8 "Kinds of Irregular Preterit" I have trouble understanding how to recognize I verbs, U verbs, J verbs from various verbs in the infinitive. I am a beginner in the Spanish language and it would be greatly appreciated if someone can help me out. Gracias.

It would be better if you could put some examples on some specific verbs that you need help first. That way it is easier to address you an answer. - scat401, Jul 21, 2011

Answer 1

I think you are referring to recognizing stem changing verbs. You just have to start by learning them, and eventually you realize there are definite patterns, so that you can unconsciously conjugate new verbs correctly. There is no magic though, except the magic of pattern.

Answer 2

HI, When you learn Spanish stem changing verbs you learn them by memorizing groups of verbs that have the stem change. You might want to search for "stem changing verbs in Spanish" and you will be able to see lists of verbs under each category.
