Cover taken by a duck at the bathing place (3)
I believe the answer is:
lid
'cover' is the definition.
(I know that lid is a type of cover)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for lid that I've seen before include "Hinged or removable cover as for bottle" , "Removable cover of a container" , "Kind of cover, may be hinged" , "Pie crust; cover" , "Bottle or jar top" .)
