Etiquette surrounding university discussion group (5)
I believe the answer is:
forum
'discussion group' is the definition.
(I've seen this before)
'etiquette surrounding university' is the wordplay.
'etiquette' becomes 'form' (I've seen this before).
'surrounding' means one lot of letters goes inside another.
'university' becomes 'u' (abbreviation for university).
'form' placed around 'u' is 'FORUM'.
(Other definitions for forum that I've seen before include "Meeting for debate" , "Place where public discussion is held, as in ancient Rome" , "Internet message board" , "A meeting to exchange views" , "place for debate" .)
