A container of cabbages (3)
I believe the answer is:
bag
'a container' is the definition.
(I know that bag is a type of container)
'of cabbages' is the wordplay.
'of' indicates a hidden word.
'BAG' can be found hidden inside 'cabbages'.
(Other definitions for bag that I've seen before include "Item of luggage; catch and kill (an animal)" , "Reserve (colloq.)" , "Valise" , "Carrier" , "Container for holding or carrying" .)
