Leave, being divided (5)
I believe the answer is:
split
I believe this clue is a double definition.
'leave' is the first definition.
(I've seen this before)
'being divided' is the second definition.
(similar in meaning)
(Other definitions for split that I've seen before include "Crack; divide" , "Balkan town" , "Break open suddenly" , "Fork" , "shared by a couple?" .)
