grimoire

Origin

Borrowed from French grimoire, a variant of grammaire, from Old French gramaire (“grammar; grimoire; conjurer, magician”), from Latin grammatica (“grammar; philology”), from grammaticus (“relating to grammar, grammatical”), from Ancient Greek γρᾰμμᾰτῐκός (grămmătĭkós, “knowing one's letters; concerned with textual criticism”), from γράμμα (grámma, “that which is drawn or written; letter; book, writing”) + -ῐκός (-ĭkós, suffix added to noun stems to form adjectives).
