Learning issue involves character associated with Reading University (9)
I believe the answer is:
erudition
'learning' is the definition.
(I know that learning can be written as erudition)
'issue involves character associated with reading university' is the wordplay.
I cannot quite see how this works, but
'character' could be 'u' and 'u' is located in the answer.
'reading' could be 'r' (one of the traditional three R's of education) and 'r' is found in the answer.
'issue' could be 'edition' (edition is a kind of issue) and 'edition' is present in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for erudition that I've seen before include "being widely read" , "Knowledge, learning" , "State of learning or culture" , "Great learning" , "Great knowledge" .)
