Security around university that may make someone blush (5)
I believe the answer is:
guilt
'security around university that may make someone blush' is the definition.
The answer and definition can be both feelings as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'security around university' is the wordplay.
'security' becomes 'gilt' (I can't explain this - if you can you should believe this answer much more).
'around' indicates putting letters inside.
'university' becomes 'u'.
'gilt' enclosing 'u' is 'GUILT'.
Can you help me to learn more?
(Other definitions for guilt that I've seen before include "uncomfortable feeling" , "Consciousness of one's wrongdoing" , "(Shame for) criminality" , "State of having committed offence" , "(Feeling induced by) wrongdoing" .)
