Get rid of scholar no longer showing benefits of education? (10)
I believe the answer is:
obliterate
'get rid' is the definition.
(I've seen this before)
'longer showing benefits of education?' is the wordplay.
'longer' becomes 'ob' (I can't explain this - if you can you should give a lot more credence to this answer).
'showing benefits of education?' becomes 'literate'.
'ob'+'literate'='OBLITERATE'
'of scholar no' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for obliterate that I've seen before include "get rid of" , "rub out" , "Destroy all traces" , "Wipe out" , "Root out" .)
