Heroic term interchangeable with "Centre of roundabout west of Paris" (3,2,8)
I believe the answer is:
arc de triomphe
'paris' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see an association between them that I don't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for arc de triomphe that I've seen before include "Feature in Paris" , "war memorial" , "Central Paris landmark" , "Paris landmark; dirt cheap, Rome (anag.)" , "Parisian landmark" .)
