Swallow's path? (6)
I believe the answer is:
gullet
'swallow's path?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
This is all the clue.
Can you help me to learn more?
(Other definitions for gullet that I've seen before include "Food-passage from mouth to stomach" , "Food passage in the throat" , "part of canal" , "Oesophagus" , "Food passage from mouth to stomach" .)
