Abuse for every head of department around university (11)
I believe the answer is:
persecution
'abuse' is the definition.
(I know that persecution is a type of abuse)
'every head of department around university' is the wordplay.
'every' becomes 'per' ('per' means 'for each' or 'for every').
'head of department' becomes 'section' (I can't explain this - if you can you should give a lot more credence to this answer).
'around' means one lot of letters goes inside another.
'university' becomes 'U' (abbreviation as in UMass).
'section' enclosing 'u' is 'secution'.
'per'+'secution'='PERSECUTION'
'for' is the link.
Can you help me to learn more?
(Other definitions for persecution that I've seen before include "Ill-treatment on e.g. religious grounds" , "Harassment" .)
