College graduate sick about having nothing left (7)
I believe the answer is:
balliol
'college' is the definition.
(Balliol College, Oxford)
'graduate sick about having nothing left' is the wordplay.
'graduate' becomes 'BA' (someone with a Bachelor of Arts degree).
'sick' becomes 'ill' (similar in meaning).
'about' is a reversal indicator.
'having nothing left' becomes 'ol' (I am not sure about this - if you are sure you should believe this answer much more).
'ill' in reverse letter order is 'lli'.
'ba'+'lli'+'ol'='BALLIOL'
Can you help me to learn more?
(Other definitions for balliol that I've seen before include "Wycliffe and Jowett were both Masters of this Oxford college" , "C13 Oxford college" .)
