What is a familiar?

 The term "familiar" is derived from the Latin word familiaris, meaning ''domestic.'' This suggests that the spirit is considered a close companion or friend. A familiar spirit, also known as a familiar or spirit guide, is a supernatural being that is believed to assist an individual on their spiritual journey. Familiars have been associated with various cultures and religious traditions, including western European mythology, Wicca, witchcraft, and medieval demonology. They accompany witches, sorcerers, or other ''cunning folk'' and provide them with magical powers, guidance, protection, or healing.

In most cases, the spirit takes the form of a small animal, such as a cat, toad, dog, bird, hyena, owl, or baboon. In some cultures, familiars may also take on a human, fairy, or imp form.

The origin of familiar spirits is not entirely clear, as the concept has been present in various cultures and religious traditions for centuries. The concept of a spirit guide can be traced back to ancient civilizations, such as the Egyptians and the Celts. These cultures believed in spirits and deities that could be summoned in times of need.
