I need to translate "wealth," but in a sense more global than just money or material belongings. This rules out "riqueza". Some possibilities are "haber" or "caudal," but these words don't seem to have that sort of connotation in Central American Spanish.
I also need to translate "intern" and "iinternship," but not in a medical sense. The usual Spanish equivalents in Central America are respectively "practicante" and "practica." Does anyone know of any other words that could describe a person being taught a trade or profession in a situation in which he is living in a dormitory situation. "Aprendiz" is not adequate in this context.
