I believe the answer is:

'land of leprechauns' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for erin that I've seen before include "that faces Atlantic" , "Early and poetic name here" , "The Emerald Isle, in poetry" , "Ireland (poet.)" , "Literary term for Ireland" .)
