Roman territorial unit? (5)
I believe the answer is:
'territorial unit?' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'roman' is the wordplay.
'roman' anagrams to 'MANOR'.
However, I'm not clear how this is indicated.
Can you help me to learn more?
(Other definitions for manor that I've seen before include "Police district (slang)" , "Grand country house" , "Lord's estate" , "Grand but strange Roman house" , "house on estate" .)
