Etymology: Animagus is a word J. K. Rowling invented for the Harry Potter books, so its history is short and fully traceable. It first appears in "Harry Potter and the Prisoner of Azkaban," published in 1999, where the wizard Sirius Black and his friend Peter Pettigrew are described as animagi who can turn into a dog and a rat respectively. The word is a blend of "animal" and the Latin "magus," the same root that gives English "magic" and "magician," and the Latin "magus" itself came into English from Greek "magos," a term for a Persian priest. The coinage works by joining two familiar elements into a new label for a specific kind of wizard. Rowling's animagus is more than a shapeshifter: the wizard keeps a human mind inside the animal form, and the books insist that the transformation must be registered with the Ministry of Magic. That bureaucratic detail is what separates the term from older folklore about werewolves or witches who took animal shapes, which the word does not describe.

Synonyms: wizard, shape-shifter, metamorph
