A spell or bewitchment.

The term comes from the Pennsylvania Dutch, who borrowed it from their native German word for “witch,” Hexe, which in turn is derived from Old High German hagazussa or hagzissa (“hag”).

In common usage, hex means an evil spell or curse, but among the Pennsylvania Dutch, for example, a hex can
be either good or bad.

It is cast by a professional witch whose services are sought out and paid for with a donation.

Witches also are consulted to break and protect against hexes
