Muggle

A Muggle is a person who is born into a non-magical family and is incapable of 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 had to know about the wizarding world, due to their daughter being a witch). 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. 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" (witches or wizards that come from non-magic families/muggles).

Wizarding law
Since the International Statute of Wizarding Secrecy was enacted in 1692, wizards and witches have hidden the existence of magic from Muggles. Thus, most Muggles are either afraid of magic or believe it to be nothing but a childish fantasy. Wizards and witches hide their world with Muggle-Repelling Charms, and if a Muggle witnesses a magical event or sees a magical creature such as a dragon, their memories are erased. Confundus Charms are also occasionally employed to encourage Muggles to ignore any magic they witness. Violations of the Statute of Secrecy are prosecuted by the Improper Use of Magic Office, and the Misuse of Muggle Artefacts Office tries to keep bewitched items away from Muggles.

Wizards and witches thus organised their own society, known as the wizarding world, distinct from that of Muggles. There are some exclusively magical settlements, such as Hogsmeade, but also magical communities hidden within largely Muggle ones, such as in Ottery St. Catchpole and even in London. Magical people also have a separate currency system and government. The Ministry of Magic maintains relations with the Muggle Prime Minister, but they do not appear to be subordinate to the Muggle government

Overlapping of worlds
However, the Muggle and magical worlds are tied together in some ways. For instance, Muggles sometimes marry wizards or witches and thus become aware of the wizarding world, as occurred with Mr. Finnigan when he married a witch. Muggles also occasionally produce a magical child. In Britain, these Muggle-born wizards and witches will often join the wizarding world when they are invited to attend Hogwarts School of Witchcraft and Wizardry. Their parents will thus be informed of the existence of the wizarding world, and may even enter it on occasion, as Mr. and Mrs. Granger did when they accompanied their daughter and the Weasley family to Diagon Alley to shop for school supplies in 1992.

Some Muggles are aware of the magical world but, through choice, choose to ignore it, such as Vernon Dursley, who was aware his sister-in-law was a witch but otherwise remained intentionally ignorant of the wizarding world until forced to recognize it with the arrival of his nephew, Harry Potter.

In addition, there are secret connections maintained between the two societies at the governmental level; for example, the Minister for Magic occasionally consults with the Prime Minister of Great Britain on issues affecting both societies, and it's clear that the Prime Minister is aware of the wizarding world. Each Prime Minister, on the day appointed to office, gets a visit from the current Minister for Magic. The visit encompasses telling the Prime Minister of the existence of magic and that they will only ever need to meet when there is something going on in the wizarding world that might affect the muggle world.

Muggle attitude towards magic
Historically, Muggles tended to consider those who practised magic to be evil, leading to the burning of witches during the Middle Ages. In response, wizards and witches used Flame-Freezing Charms to render the fire harmless. Thus, most considered the Muggle efforts completely useless. However, such acts were part of the reason that wizards decided to go into hiding. Some innocent Muggles were being burned as witches, magical children born to Muggles were often persecuted when their magical abilities surfaced, and some Muggles tried to make magical people perform magic for their own ends.

In the modern world, few Muggles believe in magic. Some who are aware of the wizarding world are accepting of it, such as Hermione Granger's parents. Others, however, respond negatively. The Dursley family, for instance, had a "very medieval" attitude towards magic. Petunia Dursley considered her sister Lily a "freak" for her abilities, although this was originally prompted by envy of them, so she would not have thought of her sister like this if she too had had those powers. She, her husband, Vernon and son, Dudley were suspicious of magic, and thus treated their wizard nephew Harry Potter badly and distrusted anyone associated with magic. They also tried to prevent him from learning of his magical heritage, without success. Ariana Dumbledore was attacked and severely traumatised by Muggle boys after they saw her use magic and she was unable to show them how to do it. So this was not as much an act of prejudice than an act of envy, like Petunia. Tom Marvolo Riddle also once suggested that his Muggle father abandoned his pregnant wife because he discovered that she was a witch.

It has been suggested by some wizards and witches that Muggles choose, on some level, not to believe in magic, since there are inevitably some occasions at which they are exposed to magic but seem to ignore it or attribute it to other causes.

Wizarding attitude towards Muggles
Many magical people, particularly pure-bloods, consider their own world superior to that of Muggles. Some consider Muggles little better than animals and hate them. For example, Araminta Meliflua once proposed that the Ministry of Magic make Muggle-hunting legal. Dark Wizard Gellert Grindelwald originally intended to conquer the world and make Muggles subservient to wizards. Lord Voldemort and his Death Eaters killed Muggles for amusement during the First and Second Wizarding Wars. They often extend this hatred to Muggle-borns as well, considering them to be unworthy of magic and not "real" wizards or witches. During the Second Wizarding War, Muggle borns were rounded up by the Ministry of Magic (on Voldemort's orders) and accused of stealing magic from wizards.

Others, however, have more favourable opinions. The Ministry also tries to protect Muggles from the Dark Arts and other potentially harmful magic things with its Misuse of Muggle Artefacts Office. Muggle Studies is also an optional subject at Hogwarts School of Witchcraft and Wizardry that strives to educate magical children about the Muggle world and to foster understanding of it.

One witch, Carlotta Pinkstone, famously advocated for the repeal of the International Statute of Wizarding Secrecy. She believed in the idea that Muggles should know about magic, and performed magic publicly on several occasions.

Arthur Weasley is very interested in how Muggles function without the aid of magic, and collects Muggle items. He has a large collection of batteries and electric plugs. He was ecstatic to meet Hermione Granger's Muggle parents, inviting them to have a drink with him at the Leaky Cauldron. During Harry Potter's stays at the Burrow, Arthur likes to sit next to Harry, in order to ask questions about Muggles. He is also interested to learn how the Muggle post office and a telephone work.

Some Muggle pastimes have also found favour with those in the wizarding world. Famously, Albus Dumbledore's Chocolate Frog Card proclaims his liking of the Muggle sport of ten-pin bowling, and he also developed a fondness for a Muggle sweet called sherbet lemon. Some elements of Muggle pop culture have also bled over into wizarding culture, such as rock and roll music which is performed by groups such as the Weird Sisters. The concept of "tabloid journalism" is also alive in the wizarding world.

Such wizards and witches are considered "blood traitors" by prejudiced pure-bloods such as the Malfoy and Black families for their belief in Muggle equality and attempts to protect them. Brutus Malfoy once claimed that it was a sign of weak magic to enjoy the company of Muggles, and his descendant Lucius Malfoy tried to sabotage Arthur Weasley's career after he proposed the Muggle Protection Act in 1992.

Etymology
Muggle is derived from the word "mug," which refers to a gullible person. J. K. Rowling has commented that she added a syllable to soften the word, which she wanted to suggest "both foolishness and lovability."
