A banshee is a female spirit from Irish and broader Gaelic folklore whose terrifying wail is said to warn that someone is about to die.

What “banshee” literally means

  • The word comes from Irish bean sí or bean sídhe , which means “woman of the fairy mound” or “fairy woman.”
  • In folklore, that connects her to the fairy or spirit world rather than to ordinary ghosts.

What a banshee is in folklore

  • She is described as a supernatural woman who appears or is heard near certain families when a death is approaching.
  • Her main “sign” is her sound: a chilling scream, wail, or keening cry that is mournful rather than simply loud.
  • In some older stories, she can appear as a beautiful young woman, a sorrowful middle‑aged woman, or an old hag, always linked to mourning and fate.

Modern usage of “banshee”

  • In everyday English, people often say someone is “screaming like a banshee” to mean they are yelling very loudly or wildly.
  • The word also shows up in games, anime, and paranormal forums as a general “scary wailing spirit,” though the original meaning is specifically Irish/Gaelic.

Tiny story-style example

Imagine a quiet farmhouse in rural Ireland centuries ago:

A family sits by the fire when, outside in the dark, a single, long, broken cry rises over the fields. The sound is not quite human, not quite animal—just a drawn-out, heart‑ripping wail. The family falls silent. No one needs to say the word “banshee.” By their lore, they already know: within days, someone under that roof will not be there anymore.

Quick TL;DR:
“Banshee” means “fairy woman” in Irish and refers to a female spirit whose mournful wail warns that a member of a family will soon die; nowadays it’s also used for anyone screaming very loudly.
