Panel hearing starts when speaker left out food server (7)
I believe the answer is:
pharynx
'panel' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for pharynx that I've seen before include "Link between mouth and oesophagus" , "Part of the throat" .)
