An incantation or enchantment is a charm or spell created using words. An incantation may take place during a ritual, either a hymn or prayer, and may invoke or praise a deity. In magic, occultism, and witchcraft it is used with the intention of casting a spell on an object or a person and may employ the use of pharmakeia. The term derives from Latin "incantare" (tr.), meaning "to chant (a magical spell) upon," from in- "into, upon" and cantare "to sing".

In medieval literature, folklore, fairy tales and modern fantasy fiction, enchantments (from the Old French "enchantement") are charms or spells. The term was loaned into English since around AD 1300. The corresponding native English term being "galdor" "song, spell". It has led to the terms "enchanter" and "enchantress", for those who use enchantments.
