Most of the literature previously in America (7)
I believe the answer is:
chicago
'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 don't see?
'most of the literature previously' is the wordplay.
'most of the literature' becomes 'chic' (I can't justify this - if you can you should believe this answer much more).
'previously' becomes 'ago' (I've seen this before).
'chic'+'ago'='CHICAGO'
'in' is the link.
Can you help me to learn more?
(Other definitions for chicago that I've seen before include "America's Windy City" , "Musical (in Illinois?)" , "Al Capone's city" , "US city - musical featuring All That Jazz" , "Illinois port" .)
