Staff assume Alexander's home (7)
I believe the answer is:
macedon
'alexander's home' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'staff assume' is the wordplay.
'staff' becomes 'mace' (a mace is a ceremonial staff or stick).
'assume' becomes 'don' (I've seen this before).
'mace'+'don'='MACEDON'
Can you help me to learn more?
(Other definitions for macedon that I've seen before include "Alexander the Great's country" , "Kingdom of Alexander the Great" , "Philip's rule" , "Philip's place" .)
