learning

I'm a little stuck... Click here to teach me more about this clue!

'erudition' is the definition.
(I know that erudition can be written as learning)

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for learning that I've seen before include "Instruction" , "Researching - scholarship" , "Cognitive process of acquiring skill or knowledge" , "Acquired knowledge" , "The gaining of knowledge" .)

I've seen this clue in The Globe and Mail.
