Go away, leave (6)
I believe the answer is:
depart
I believe this clue is a double definition.
'go away' is the first definition.
(synonyms)
'leave' is the second definition.
(I know that leave can be written as depart)
(Other definitions for depart that I've seen before include "Go away or leave" , "make tracks" , "Retire from" , "Prated (anag.)" , "Quit" .)
