Purveyor of food says it's even more disgusting (6)
I believe the answer is:
grocer
'purveyor' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for grocer that I've seen before include "Retail merchant" , "Market trader" , "Seller of food and household supplies" , "Chesterton's wicked tradesman" , "Food merchant" .)
