Group of academics pass on a bit of erudition (7)
I believe the answer is:
college
'group of academics' is the definition.
'college' can be an answer for 'group' (thesaurus). I'm not certain of the 'of academics' bit.
'pass on a bit of erudition' is the wordplay.
'pass' becomes 'col' (col is a term for a mountain pass).
'on' becomes 'leg' (cricket term, fielding positions).
'a bit of' suggests taking the first letters.
The first letter of 'erudition' is 'e'.
'col'+'leg'+'e'='COLLEGE'
Can you help me to learn more?
(Other definitions for college that I've seen before include "Jesus or Magdalene, for example" , "Educational institution" , "Institution of higher education" , "eg Eton" , "Where one learns" .)
