What's in a Name?

What’s a magical name? How do I get one? And why are so many Wiccans named Raven?

A magical name—or craft name, as they are sometimes called—is a name you take on when you become a Wiccan, and it’s the name other Wiccans in the community will know you by and that you will use in Wiccan rituals. Some people take on a name when they first become interested in Wicca. Others wait until they dedicate themselves to the path through a self-dedication ceremony or when they are initiated into a particular Wiccan group. Some Wiccan traditions (traditions are kind of like denominations in Christianity) have special rules for when someone takes a name and what kind of name it can be, and others don’t. And in some cases your name might be bestowed on you by a teacher, but this practice is not very common anymore.

Most Wiccans who have magical names only use them in the Wiccan community, and use their legal names elsewhere. Having a second name can help protect your privacy in case there are people you don’t want to know about your Wiccan practice. However some Wiccans use their magical names all the time, even outside of the Wiccan community, and some only use theirs when they are in ritual space.
