Lily Potter, born Evans, is a witch. She was a talented and skilled witch who attended Hogwarts School of Witchcraft and Wizardry, where she was in Gryffindor House. Lily married James Potter, who was also a wizard, and together they had a son named Harry Potter, who famously defeated the dark wizard Voldemort. Lily's magical abilities and involvement in the wizarding world make her a witch, not a Muggle. **

In the Harry Potter series, a Muggle-born is often referred to as a "Mudblood." This term is considered derogatory and offensive, as it is used by some characters to belittle and discriminate against those who have magical abilities despite being born to non-magical parents. The term reflects the prejudice and discrimination that exists within the wizarding world against those who come from non-magical backgrounds. **

The letters from Hogwarts to Muggle-born students are called "Hogwarts acceptance letters." These letters are sent to inform Muggle-born students that they have been accepted to Hogwarts School of Witchcraft and Wizardry and provide them with all the necessary information for their enrollment at the school. The letters are delivered by owl post and are a magical and exciting way for Muggle-born students to learn about their acceptance into the wizarding world. **

A child born to a Squib with another Squib or a Muggle is not guaranteed to be magical. The likelihood of the child being magical depends on whether the non-Squib parent carries the wizarding gene. If the non-Squib parent is a witch or wizard, there is a chance that the child could be magical. However, if both parents are Squibs or Muggles, the child is unlikely to possess magical abilities. **

The question about Harry Potter with half-blood, Muggle-born, and pure-blood background is related to the concept of blood status in the wizarding world. It explores the significance of a character's magical lineage and how it impacts their identity and experiences within the magical community. This theme is central to the series as it delves into issues of prejudice, discrimination, and the complexities of identity. The question also raises discussions about the representation of social and political issues within the context of a fantasy narrative. **

Yes, Muggle-borns are allowed in Slytherin house at Hogwarts. While Slytherin is known for valuing pure-blood heritage, the Sorting Hat takes into account a student's traits and qualities rather than their blood status when placing them in a house. Muggle-borns who exhibit ambition, cunning, and resourcefulness may find themselves sorted into Slytherin. **

Yes, Muggle-borns can come to Slytherin. The Sorting Hat takes into account a student's qualities and values, not their blood status. Slytherin values ambition, cunning, and resourcefulness, which can be found in students from all backgrounds, including Muggle-borns. As long as a Muggle-born student embodies these traits, they can be sorted into Slytherin house. **

No, Expelliarmus does not work on Muggle weapons. Expelliarmus is a spell used in the wizarding world to disarm an opponent by causing their wand to fly out of their hand. It is specifically designed to work on magical objects, such as wands, and does not have any effect on non-magical items like Muggle weapons. Therefore, if a wizard were to use Expelliarmus on a Muggle holding a gun, for example, it would have no effect on the gun itself. **
