Irish wailer (7)
I believe the answer is:
banshee
'irish wailer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for banshee that I've seen before include "Wailing woman of Irish legend" , "Wailing woman warning of a death" , "Mythical Gaelic wailing woman" , "Wailing female spirit" , "Sign of imminent death" .)
