Arrange about a place in America (7)
I believe the answer is:
seattle
'america' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'arrange about a place in' is the wordplay.
'arrange about' becomes 'a' (I can't explain this - if you can you should believe this answer much more).
'a place' becomes 'settle' (I've seen this before).
'in' indicates putting letters inside.
'a' inserted inside 'settle' is 'SEATTLE'.
Can you help me to learn more?
(Other definitions for seattle that I've seen before include "City of north-west USA" , "major US port" , "U S west coast city" , "Port of north-west USA" , "Let's eat at this US city" .)
