“ Powerful spells are bound by something even more powerful… the moon, acomet, a doppelgänger. The Other Side was made 2,000 years ago, and it still exists. That means she must have bound it to something that could exist just as long. ”
— Bonnie Bennett in Monster's Ball

One of the defining characteristics of a witch is their ability to cast spells; a "spell" being the word used to signify the means employed to carry out a magical action. A spell could consist of a ritual action, a set of words, a verse, or any combination of these, many of which are archived in books known as Grimoires.
For reasons unknown, the majority of spells used by practitioners of Spirit Magic and Traditional Magic are spoken in an ancient language very similar to Latin. However, witches who practice other forms of magic have been known to use spells in different languages; for example, the New Orleans Coven, which practices Ancestral Magic, performs their spells in French or French Creole, while the Travelers, practicing Traveler Magic, typically perform their spells in Czech. Dahlia and Freya Mikaelson has shown to perform spells using an yet to be identified Ancient Magic in Old Norse, similar to the modern-day Norwegian, Icelandic, Faroese, Danish and Swedish.
