Untidy about the neck? (7)
I believe the answer is:
scruffy
'untidy' is the definition.
(similar in meaning)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for scruffy that I've seen before include "Untidy, dirty" , "Unkempt" , "Ill-groomed" , "Shabby and untidy" , "Female deer" .)
