Scruff of the neck (4)
I believe the answer is:
nape
'scruff of the neck' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for nape that I've seen before include "Here's a hairline" , "Scrag" , "Girl personifying France" , "Scruff of the neck" , "Back part of the neck" .)
