Old Italian renovated manor (5)
I believe the answer is:
roman
'old italian' is the definition.
(I've seen this before)
'renovated manor' is the wordplay.
'renovated' indicates anagramming the letters.
'manor' with letters rearranged gives 'ROMAN'.
(Other definitions for roman that I've seen before include "Classical" , "French story" , "Denizen of the eternal city" , "Like the English alphabet" , "Type of candle, nose etc" .)
