[quote=http://www.ew.com/article/2015/11/04/fantastic-beasts-american-muggle]Next year’s Harry Potter prequel film Fantastic Beasts and Where to Find Them is set in 1926 New York, where the wizarding community uses another term entirely for people without magical powers. 

In shifting the franchise away from the U.K., author J.K. Rowling — who also wrote the movie’s screenplay — is poised to introduce several new words into the Potterverse lexicon, and [b]the most significant might be what Stateside wizards say instead of Muggle: “No-Maj” (pronounced “no madge,” as in “no magic”)[/b].[/quote]
And now you know.
