Wicca is a religion based on the perception of ancient pre-Christian magical and spiritual practices.
The name of the religion is taken from an ancient name for cunning folk or witches.
Many people use the words Wicca and Witchcraft interchangeably, which makes sense etymologically but not always practically.
There are many people who practice witchcraft who are not Wiccan.
It was once said that every Wiccan is also a Witch, but some Wiccans do not actively practice Witchcraft beyond performing the magico-religious rituals prescribed by the religion.
