Where certain chessmen are bred? (7)
I believe the answer is:
rookery
'where certain chessmen are bred?' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
This is the entire clue.
Can you help me to learn more?
(Other definitions for rookery that I've seen before include "Nesting-place" , "Breeding-place of birds, penguins, seals" , "Seal, penguin, colony" , "Community of birds" , "breeding ground" .)
