spell, word, formula, or incantation believed to have magical powers. The spell can be used for evil or good ends; if evil, it is a technique of sorcery. Many authorities believe that the spell was the precursor of prayer. In Teutonic lore, the spell was a form of exercising occult power and was sometimes used to summon the spirits of departed heroes to give prophetic utterances. Once cast, the spell was supposed to remain in force until broken by a counterspell or exorcism.
