Gaelic name for Ireland (4)
I believe the answer is:
eire
'gaelic name for ireland' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eire that I've seen before include "Gaelic name for Republic of Ireland" , "Official name of the Irish Republic, 1937-49" , "Republic across the water" , "Southern Ireland" , "Former name of the Irish Republic" .)
