Muggle

A Muggle is a person who is born into a non-magical family and is incapable of performing  magic. Most Muggles are not aware that magic exists at all and that those with it have organised their own society largely separate from the Muggle world. The few Muggles that do know of the existence of the wizarding world are usually parents, or close relatives, of witches and wizards (for example, Hermione Granger's parents, Mr and Mrs Granger, knew of the wizarding world because of their daughter, as did Harry Potter's aunt and uncle). Muggles are not to be confused with Squibs, who also lack magic but are born into magical families and are aware of the wizarding world. The term "Muggle" is widely used in the wizarding world, and generally is not intended to be offensive; in fact, it is often used affectionately, often by Arthur Weasley, who has a great fondness for Muggles and learning about them and their way of life. Some of the more prejudiced members of the community, however, use the word in the same context as the epithet "Mudblood," though the term is generally associated with Muggle-borns.
