what is banshee

A banshee is a supernatural female spirit from Irish and Gaelic Celtic folklore known for heralding the death of a family member, often by wailing, screaming, or keening. The term "banshee" derives from the Irish phrase bean sídhe , meaning "woman of the fairy mounds" or "fairy woman." Banshees are believed to be connected to certain families, especially those of pure Irish descent, and their mournful cries serve as a warning of impending death in a household. Though often thought of as ghosts or spirits, linguistically banshees are considered fairies, remnants of ancient Irish deities (Tuatha Dé Danann) who were relegated to fairy status. Some folklore also describes related supernatural beings like the baobhan sith, a vampire-like fairy woman who feeds on blood. The banshee's role is primarily one of warning, not malevolence, and she is a deeply rooted figure in Celtic mythology and folklore.
