Empty net (5)
I believe the answer is:
clear
I believe this is a double definition.
'empty' is the first definition.
(I know that clear is a type of empty)
'net' is the second definition.
(I know that net can be written as clear)
(Other definitions for clear that I've seen before include "Plain; unblock" , "Fine" , "Plainly" , "School near Windsor" , "Unambiguous" .)
