Pureblood
"Pureblood" typically refers to individuals or families in the Harry Potter series who have no known Muggle ancestry, meaning all their ancestors are wizards or witches. This term is often associated with a sense of superiority among some characters, who believe that being a Pureblood makes them more powerful or prestigious within the wizarding community.
In the context of the series, Purebloods are often contrasted with Muggle-borns, who are born to non-magical parents but possess magical abilities. The concept of Pureblood status plays a significant role in the themes of prejudice and discrimination throughout the Harry Potter narrative.
