A stirring race meeting? (7,3)
I believe the answer is:
melting pot
This could be a double definition.
'a stirring race' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'meeting?' is the second definition.
The answer and definition can be both locations as well as being singular nouns.
Maybe you can see an association between them that I don't see?
(Other definitions for melting pot that I've seen before include "Crucible'" , "Place where different peoples mix" , "Vessel - place for mixture" , "In which to mix metals, immigrants" , "Place where different peoples mingle" .)
