Food seller (6)
I believe the answer is:
grocer
'food seller' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for grocer that I've seen before include "Shopkeeper who sells food and household goods" , "Shopkeeper who sells food and household stores" , "Retailer of foodstuffs" , "Provision merchant" , "Food dealer" .)
