Part of the palate
I believe the answer is:
uvula
'part of the palate' is the definition.
('uvula' is part of 'palate')
This is all the clue.
(Other definitions for uvula that I've seen before include "Fleshy part of the palate" , "Fleshy body over back of tongue" , "Fleshy lobe" , "Part of one's mouth" , "Fleshy projection hanging from roof of mouth" .)
