Violet city (5)
I believe the answer is:
parma
This clue could be a double definition.
'violet' is the first definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'city' is the second definition.
(I have seen 'Italian city' mean 'parma' so perhaps 'city' could also mean 'parma')
Can you help me to learn more?
(Other definitions for parma that I've seen before include "Italian city noted for ham" , "It. ham city; its Charterhouse, Stendhal" , "Italian city producing cured ham" , "Here in Italy" , "European city" .)
