Variation of normal, abridged Italian (5)
I believe the answer is:
roman
'italian' is the definition.
(someone from Rome)
'variation of normal abridged' is the wordplay.
'variation of' indicates anagramming the letters (I've seen 'variations' mean this).
'abridged' means to remove the last letter.
'normal' with its final letter taken away is 'norma'.
'norma' anagrammed gives 'ROMAN'.
(Other definitions for roman that I've seen before include "Caesar, for instance" , "Printing style" , "eg Julius Caesar" , "- Catholic; - candle" , "See 19" .)
