Young wise friend (is there a one word discription)
Abuelo - means grandfather or respected old man
is there a word for "young respected friend"
Sabiduroso...which is to say a wise person, with the implication of youth. But I agree with Philmikki...and moreover, I don't think you can use them together in english, eihter
I'd use Hijo Sabio probably. Sort of like a child genius, or young wiseman if you will.
I don't think you are allowed to use those two words in the same sentence in Spanish.
