Go away from academic room in the morning (5)
I believe the answer is:
scram
'go away' is the definition.
(scramming is a kind of going away)
'academic room in the morning' is the wordplay.
'academic room' becomes 'scr' (senior common room at a university).
'in the morning' becomes 'am' ().
'scr'+'am'='SCRAM'
'from' acts as a link.
(Other definitions for scram that I've seen before include "Make oneself scarce" , "Vamoose" , "Leave hurriedly" , "Clear off!" , "beat hasty retreat" .)
