National, say, location for operational staff (7)
I believe the answer is:
theatre
This clue could be a double definition.
'national say location' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'operational staff' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'for' is the link.
Can you help me to learn more?
(Other definitions for theatre that I've seen before include "natural land formation?" , "where Finney played" , "Building for plays or operations" , "Scene of plays" , "Audience" .)
