In Turkic cultureEdit
In Turkic (usually neighboring Slavic) folklore its name is Chor (In Turkish and Azerbaijan languages: Çor). In Anatolia known as Chorabash. Chors are spiritual creatures mentioned in the pre-Islamic texts and oral tradition who inhabit an unseen world in dimensions beyond the visible universe of humans. Folk narratives mentions that the Chors are made of fire, but also physical in nature, being able to interact physically with people and objects and likewise be acted upon. Like human beings, the Chor can also be good (Ak-çor "White-Chor"), evil (Kara-çor "Black-Chor"), or neutrally benevolent and hence have freewill like humans and unlike angels. The exorcist are called Çoraman in Anatolia.
There are many theories regarding the origins of the Proto-Slavic word *čьrtъ. One is that it's a substantivized t-participle of *ker- (to cut, to chop), which could be derived from chorts imagined as being lame (having one leg shorter). The words like Ukrainian kutsiy and Czech kusý, also derived from *ker-, are one of chort's most common epithets.
