Irish wailing woman (7)
I believe the answer is:
banshee
'irish wailing woman' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for banshee that I've seen before include "Wailing Irish sprite" , "Wailing female spirit" , "Irish female spirit who warns of an impending death" , "Ominous wailing spirit" , "Wailing woman from Gaelic myth" .)
