Is able to provide a container (3)
I believe the answer is:
can
This clue is a double definition.
'is able to' is the first definition.
(if you can do something you are able to do it)
'a container' is the second definition.
(I know that can is a type of container)
'provide' is the link.
(Other definitions for can that I've seen before include "Billy" , "prison" , "let go in the US" , "Metallic container" , "John" .)
