"Give" is straightforwardly ofan in any simple tense and any person. A common paraphrase for "X teaches Y about Z" is X bolaav onikaan do Z fah Y, "X grants wisdom of Z to Y"

Frinmulaar is right, that is the most common phrase for teaching. However, the phrase X ofan mindoraan do Z fah Y ("X gives understanding of Z to Y") works too, although that has a slightly different connotation to it. Use whichever you think would fit better in the context of your story.
