Erudition, knowledge (8)
I believe the answer is:
learning
This clue is a double definition.
'erudition' is the first definition.
(I know that erudition can be written as learning)
'knowledge' is the second definition.
(I know that learning is a type of education)
(Other definitions for learning that I've seen before include "Lore" , "Cognitive process of acquiring skill or knowledge" , "The gaining of knowledge" , "Researching - scholarship" , "information" .)
