Where to go for the jugular (4)
I believe the answer is:
neck
'where to go for the jugular' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for neck that I've seen before include "and what is at the bottom of it" , "Cervix" , "sink" , "Head supporter" , "that's inserted in collar" .)
