Italy's capital, to natives (4)
I believe the answer is:
roma
'italy's capital to natives' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for roma that I've seen before include "Travelling people" , "Travellers, gypsies" , "Members of a nomadic people" , "capital for > gypsy men" , "Travellers; Italian capital" .)
