Separated and left (6)
I believe the answer is:
parted
This clue is a double definition.
'separated' is the first definition.
('part' can be a synonym of 'separate')
'left' is the second definition.
(parting is a kind of leaving)
'and' acts as a link.
(Other definitions for parted that I've seen before include "Divided, broken" , "Divided and said goodbye" , "Split up, separated" , "One's hair might be" , "Divided or went separate ways" .)
