As I understand it, the word 学際 is usually used to mean "interdisciplinary" when referring to college courses. However, I recently came across the word "超域文化科学" while browsing college websites. In this context, 超域 seems to mean "interdisciplinary" too, but I'm not 100% sure.
What exactly is 超域, how is it different from 学際 and how is it pronounced?
