Tutor group encapsulating university place of debate (5)
I believe the answer is:
forum
'place of debate' is the definition.
(a forum is a place for discussion)
'tutor group encapsulating university' is the wordplay.
'tutor group' becomes 'form' (as in a form group at school).
'encapsulating' means one lot of letters goes inside another (I've seen this in other clues).
'university' becomes 'u' (abbreviation for university).
'form' going around 'u' is 'FORUM'.
(Other definitions for forum that I've seen before include "A meeting to exchange views" , "Place where public discussion is held, as in ancient Rome" , "Place to meet people" , "Online message board" , "Place of assembly for the people in ancient Greece" .)
