Island near Naples (5)
I believe the answer is:
capri
'island near naples' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for capri that I've seen before include "Neapolitan isle" , "popular resort" , "Italian resort island, once home to Gracie Fields" , "Greek island" , "Old Ford model - Italian island" .)
