Somewhere to discuss university cutting class? (5)
I believe the answer is:
forum
'somewhere to discuss' is the definition.
(a forum is a place for discussion)
'university cutting class?' is the wordplay.
'university' becomes 'u' (abbreviation for university).
'cutting' is an insertion indicator (some letters cut their way into a word).
'class?' becomes 'form' ('form' can be a synonym of 'class').
'u' put within 'form' is 'FORUM'.
(Other definitions for forum that I've seen before include "Public meeting-place for open discussion" , "Place where public meeting or discussion is held" , "Place of assembly for the people in ancient Greece" , "Place for open discussion" , "Internet message board" .)
