Reminder about university being complacent (5)
I believe the answer is:
proud
'complacent' is the definition.
(thesaurus)
'reminder about university' is the wordplay.
'reminder' becomes 'prod' (I've seen this before).
'about' indicates putting letters inside.
'university' becomes 'u' (abbreviation for university).
'prod' going around 'u' is 'PROUD'.
'being' is the link.
(Other definitions for proud that I've seen before include "Haughty - sticking out" , "Pleased by one's own achievements" , "Having a high opinion of oneself" , "With high self-opinion" , "Feeling gratified or arrogant" .)
