Italian from Ancona boxes (5)
I believe the answer is:
roman
'italian' is the definition.
(Roman is an example)
'from ancona boxes' is the wordplay.
'boxes' indicates a hidden word (to box can mean to contain).
'ROMAN' is hidden within 'from ancona'.
(Other definitions for roman that I've seen before include "Countryman of Mark Antony" , "Old Italian l" , "Classical" , "Printing style" , "Caesar, for instance" .)
