Left like some combed hair? (6)
I believe the answer is:
parted
'left' is the definition.
(parting is a kind of leaving)
'some combed hair?' is the wordplay.
'some' becomes 'part' (only part of something).
'combed hair?' becomes 'ed' (I can't justify this - if you can you should give a lot more credence to this answer).
'part'+'ed'='PARTED'
'like' is the link.
Can you help me to learn more?
(Other definitions for parted that I've seen before include "Divided or separated" , "Divided and said goodbye" , "left" , "Divided or went separate ways" , "Divided, broken" .)
