Endlessly feast on French writer's cheese (10)
I believe the answer is:
gorgonzola
'endlessly feast' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'on french writer's cheese' is the wordplay.
'on' says to put letters next to each other.
'french writer' becomes 'zola' (I've seen this before).
'cheese' becomes 'gorgon' (I have seen 'Italian cheese ' mean 'gorgon' so perhaps 'cheese' could also mean 'gorgon').
'zola' after 'gorgon' is 'GORGONZOLA'.
Can you help me to learn more?
(Other definitions for gorgonzola that I've seen before include "Italian town" , "Italian blue cheese" , "Big cheese" , "Blue-veined cheese" .)
