Some words that Hogwarts used, MMA used different words for: MMA said nonmagical instead of Muggle, and first-generation magical (or first-gen) instead of Muggle-born. However, instead of inventing different words for Pureblood and half-blood, MMA did not use those words at all. As Headmistress Norwood put it, "Miss Granger, Hogwarts would describe you as a "Muggle-born’—when they weren’t insulting you with that other word—and Hogwarts would describe you, Mr Potter, as a "Muggle-raised half-blood.’ Emily, myself, and Miss Burke, the Arithmancy Professor, are the only people in this school who understand what those words mean. But what those words mean, doesn’t matter in this school. Mr Potter isn’t entitled to better treatment here because he has blood of more "magical purity,’ nor is Miss Granger entitled to better treatment here because her blood is more nonmagical."
