A ponytail hangs over it (4)
I believe the answer is:
nape
'a ponytail hangs over it' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nape that I've seen before include "Girl personifying France" , "It's a pane in the neck" , "Scrag" , "Scruff of the neck" , "Here's a hairline" .)
