Where Americans pay bills around mid-May (7)
I believe the answer is:
seattle
'where americans pay bills around mid-may' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
This is all the clue.
Can you help me to learn more?
(Other definitions for seattle that I've seen before include "US Pacific port" , "U S west coast city" , "? American seaport" , "Sleepless in --, film" , "American city" .)
