Left divided (6)
I believe the answer is:
parted
I believe this is a double definition.
'left' is the first definition.
(parting is a kind of leaving)
'divided' is the second definition.
('part' can be a synonym of 'divide')
(Other definitions for parted that I've seen before include "left" , "Divided or went separate ways" , "One's hair might be" , "Split up, separated" , "Divided or separated" .)
