Inclination to take in right erudition (8)
I believe the answer is:
learning
'erudition' is the definition.
(I know that erudition can be written as learning)
'inclination to take in right' is the wordplay.
'inclination' becomes 'leaning' (incline can mean to lean).
'to take in' indicates putting letters inside.
'right' becomes 'r' (common abbreviation).
'leaning' placed around 'r' is 'LEARNING'.
(Other definitions for learning that I've seen before include "Discovering, finding out" , "Instruction" , "The gaining of knowledge" , "(Knowledge from) study" , "A little of it is said to be a dangerous thing" .)
