A ghoul is a monster from ancient Arabian folklore. Ghouls live in burial grounds and other uninhabited places. The English word comes from the Arabic name for the creature: الغول ghūl, which literally means "demon".[1] The ghul is a devilish type of jinn believed to be sired by Iblis.[2]
The female form is given as "ghouleh" in Muhawi and Kanaana (see ref below). The plural is "ghilan".
Ghoul is also a shapeshifting demon that lives in the desert. The demon can take the form of an animal, especially a hyena. It lures unwary travellers into the desert. It will then kill and eat them. The creature also preys on young children, robs graves, and eats the dead.[3] Because of this habit the word ghoul is sometimes used to refer to an ordinary human such as a grave robber, or to anyone who likes the macabre.
The star Algol takes its name from this creature.[4]
