book of magic spells, invocations and talismans

Grimoire is a book of witchcraft or paranormal magic. The word is pronounced "grim-warr", which rhymes with "guitar".

This design for an amulet comes from the Black Pullet grimoire.

The word is a mistaken way of saying grammar. It probably started being used in a time when not many people could read. Then any book might be thought to contain instructions for magic.

In the religion of Wicca and other forms of Neopaganism, such a book is sometimes called a "Book of Shadows".
