Appropriate interest (3)
I believe the answer is:
bag
I believe this clue is a double definition.
'appropriate' is the first definition.
(thesaurus)
'interest' is the second definition.
(I've seen this before)
(Other definitions for bag that I've seen before include "Item of luggage; catch and kill (an animal)" , "Gladstone, for example" , "Pouch" , "Reserve (colloq.)" , "Container for holding or carrying" .)
