Where sharpers would be at home? (7)
I believe the answer is:
rookery
This might be a double definition.
'where sharpers' is the first definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'at home?' is the second definition.
The definition and answer can be both locations as well as being singular nouns.
Maybe there's an association between them I don't understand?
'would be' is the link.
Can you help me to learn more?
(Other definitions for rookery that I've seen before include "breeding ground" , "Seal, penguin, colony" , "Lofty breeding-place" , "Breeding-place of birds, penguins, seals" , "Breeding colony of birds, also of seals or turtles" .)
