Italian cheese city (5)
I believe the answer is:
'italian cheese city' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for parma that I've seen before include "Italian city famous for cheese and ham" , "It. ham city; its Charterhouse, Stendhal" , "Here in Italy" , "Italian city producing cured ham" , "Italian city noted for ham" .)
