noun.
In Irish folklore, a female spirit, usually taking the form of a woman whose mournful wailing warns of an impending death. Originally a fairy woman singing a caoineadh (lament) for recently-deceased members of the O’Grady, the O’Neill, the O’Brien, the O’Connor, and the Kavanagh families, translations into English made a distinction between the banshee and other fairy folk that the original language and original stories do not seem to have, and thus the current image of the banshee.
