Italian city partly up a dual carriageway (5)
I believe the answer is:
padua
'italian city' is the definition.
(I've seen this in another clue)
'partly up a dual carriageway' is the wordplay.
'partly' indicates the answer is hidden within the clue (part of the clue is used).
'PADUA' is hidden in the letters of 'up a dual carriageway'.
(Other definitions for padua that I've seen before include "Italian city near Venice" , "North-eastern Italian city" , "City in northeast Italy" , "City of N. Italy" , "Italian city of St Anthony" .)
