<P> The term Muggle is sometimes used in a pejorative manner in the books . Since Muggle refers to a person who is a member of the non-magical community, Muggles are simply ordinary human beings without any magical powers and often without any knowledge of the magical world rather than witches and wizards . According to the author, J.K. Rowling, a quarter of the annual Hogwarts School of Witchcraft and Wizardry intake have two non-magical parents; there have also been some children known to have been born to one magical and one non-magical parent . Children of this mixed parentage are called half - bloods (strictly speaking, they are' Literal Half - bloods'); children with recent Muggle ancestry on the one side or the other are also called half - bloods . The most prominent Muggle - born in the Harry Potter series is Hermione Granger, who had two Muggles of unspecified names as parents . A witch or wizard with all magical heritage is called a pure - blood . </P> <P> In the Harry Potter books, non-magical people are often portrayed as foolish, sometimes befuddled characters, who are completely ignorant of the Wizarding world that exists in their midst . If, by unfortunate means, non-magical people do happen to observe the working of magic, the Ministry of Magic sends Obliviators to cast Memory Charms upon them causing them to forget the event . </P> <P> Some Muggles, however, know of the wizarding world . These include Muggle parents of magical children, such as Hermione Granger's parents, the Muggle Prime Minister (and his predecessors), the Dursley family (Harry Potter's non-magical and only living relatives), and the non-magical spouses of some witches and wizards . </P> <P> Rowling has stated she created the word "Muggle" from "mug", an English term for someone who is easily fooled . She added the "- gle" to make it sound less demeaning and more "cuddly". </P>
