"Neighbourhood witches" are the product of neighbourhood arguments, and are found only in rural village communities where the inhabitants largely rely on each other. Such accusations follow the breaking of some social norm, such as the failure to return a borrowed item, and any person part of the normal exchange could potentially be accused. Claims of "sorcerer" witches and "supernatural" witches could arise out of social tensions, but not exclusively; the supernatural witch in particular often had nothing to do with community conflict, but expressed tensions between the human and supernatural worlds; and in Eastern and Southeastern Europe such supernatural witches became an ideology explaining calamities that befell entire communities.
