Pleas from Neapolitans in Italy, for one (6)
I believe the answer is:
nation
'italy for one' is the definition.
(italy is a kind of nation)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for nation that I've seen before include "Anoint (anag)" , "Country, state" , "A federation of tribes, as Native Americans say" , "Large community of people under one government" , "People sharing a common culture/descent" .)
