A ghoul is a (folkloric) monster associated with graveyards and consuming human flesh, often classified as undead. The oldest surviving literature that mention ghouls is likely One Thousand and One Nights. The term was first used in English literature in 1786, in William Beckford's Orientalist novel Vathek, which describes the ghūl of Arabian folklore.
Early etymology 
In Arabian folklore 
A ghul is also a desert-dwelling, shapeshifting, evil demon that can assume the guise of an animal, especially a hyena. It lures unwary people into the desert wastes or abandoned places to slay and devour them. The creature also preys on young children, drinks blood, steals coins, and eats the dead, then taking the form of the person most recently eaten.
In the Arabic language, the female form is given as ghouleh and the plural is ghilan. In colloquial Arabic, the term is sometimes used to describe a greedy or gluttonous individual.
