Well this all depends on if people count fantasy languages or not. I can read Drow and spout off a few phrases pretty well, same with elfish. I can recognize a few other fantasy languages too but can’t understand them without looking things up.
As for “real” languages, I can understand and read a good about of Japanese and Spanish. I am working on actually learning German at the moment as it is my heritage and I thought it would be nice to learn.
