Banshee

female spirit in Irish mythology

In Celtic mythology, a Banshee is a female spirit, who usually announces that a person from the family will die soon. The word is from bean sí, which literally means woman from the hills. An older spelling is bean sidhe. Bean sith, and bean-nighe are variants.
