Grocery sack (3)
I believe the answer is:
bag
'grocery sack' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for bag that I've seen before include "Quantity of game shot in a particular period" , "interest" , "The amount of game shot by sportsman" , "Flexible container for carrying things" , "Item of luggage; catch and kill (an animal)" .)
