What is druid definition?

Druid is a member of an ancient Celtic priesthood, who were the spiritual and intellectual leaders of their communities. The name "druid" comes from the Celtic word "doire," which means "oak grove." Druids were known for their knowledge of the natural world, including plants and animals, and their ability to communicate with the spirits of the land. They performed religious ceremonies, acted as judges, and advised kings and warriors. Druidism was suppressed by the Roman Empire and later by Christianity, but a revival of interest in Celtic culture and spirituality has led to a renewed interest in druidism in modern times.
