To answer this question, you need to provide more context. What do you want to know about your uncle?
Here are some examples of how you might respond:
* "Él es mi tío." (He is my uncle.)
* "¿Qué quieres saber sobre él?" (What do you want to know about him?)
* "No lo sé." (I don't know.)
* "Él está bien." (He is fine.)
To give you the best answer, please tell me:
* What is the context of the question? Are you asked this in a conversation, a test, or another situation?
* What kind of information are you looking for? Do you want to know about his personality, his job, his relationship with your mother?
Once you provide more information, I can give you a more specific and helpful answer.
