Morphology

up + on

There is a partial cue to the meaning in the constituents: 'up' often signals being current or informed (cf. 'up-to-date'), while 'on' indicates relation to a topic. However, the exact sense 'knowledgeable about' is not fully predictable from knowing 'up' and 'on' separately and typically requires exposure to the fixed phrase, so it is only partially transparent to a B1 learner.

Etymology

Up on comes from the picture of someone standing up on a hill or roof so they can see things clearly. If you can look down and watch something, you know it well, so up on means 'well informed'.
