Front part of the neck (6)
I believe the answer is:
throat
'front part of the neck' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for throat that I've seen before include "A frog is a problem in this" , "Front part of the neck" , "Forepart of the neck" , "Passage to the stomach and lungs" , "It's inside the neck" .)
