An incantation, spell, charm, enchantment, or bewitchery is a magical formula intended to trigger a magical effect on a person or objects. The formula can be spoken, sung, or chanted. An incantation can also be performed during ceremonial rituals or prayers. In the world of magic, wizards, witches, and fairies are common performers of incantations in culture and folklore.
In medieval literature, folklore, fairy tales, and modern fantasy fiction, enchantments are charms or spells. This has led to the terms "enchanter" and "enchantress" for those who use enchantments. The English language borrowed the term "incantation" from Old French in the late 14th century; the corresponding Old English term was gealdor or galdor, "song, spell", cognate to ON galdr. The weakened sense "delight" (compare the same development of "charm") is modern, first attested in 1593 (OED).
