Representing American marketplaces (4)
I believe the answer is:
fora
'marketplaces' is the definition.
(forum is a kind of marketplace)
'representing american' is the wordplay.
'representing' becomes 'for' (I can't justify this - if you can you should believe this answer much more).
'american' becomes 'a' (common abbreviation - e.g. in organisation names).
'for'+'a'='FORA'
Can you help me to learn more?
(Other definitions for fora that I've seen before include "Discussion meetings" , "markets in Rome" , "Areas of discussion" , "Roman public squares" , "discussions here" .)
