In place of learning, rotter’s in A&E with me! (7)
I believe the answer is:
academe
'in place of learning' is the definition.
I can't judge whether this definition defines the answer.
'rotter's in ae with me' is the wordplay.
'rotter' becomes 'cad' (a cad is a dishonourable person).
'in' indicates putting letters inside.
'with' means one lot of letters go next to another.
'cad' going within 'ae' is 'acade'.
'acade'+'me'='ACADEME'
Can you help me to learn more?
(Other definitions for academe that I've seen before include "college" , "The world of scholars" , "intellectual world" , "The world of teaching" , "universities" .)
