Dublin's land, to natives (4)
I believe the answer is:
eire
'dublin's land to natives' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for eire that I've seen before include "EU country" , "Breakaway state" , "Gaelic name for Republic of Ireland" , "Irish name for Ireland" , "Southern Ireland" .)
