How do you know a stem changing verb is a stem changing verb?
I am beginning to learn about stem changing verbs. I understand the appropriate stem changes, I was just wondering how you recognize a stem changing verb? Is there a rule to know which verbs are stem changing or do you just learn and memorize from experience?
I never learned a trick, rather I developed a keen ear for what sounds right and what doesn't.
As a beginner, I learned these in school and we ended up using them so much that they got stuck in my memory. Soon I was able to figure out that "Quero just doesn't sound right, so it must be quiero."
Once you get more advanced, you may even be able to recognize that a verb changes without ever seeing it before.
That's all I got
A good and fair question. I´m sorry to report it´s mostly just memorization. Experience and practice will make it easier over time. You will start to recognize patterns over time too, and eventually won´t even think about it much.
Also, note that words, and other words with additional prefixes, will be conjugated just alike. For instance, Tener and Obtener. Poner and Suponer, etc etc.
