Halfblood vs. Pureblood?
What's the specific definition in the wizarding world of halfblood vs. pureblood? Are purebloods only those who have NEVER had a Muggle in their bloodline? Or do they consider purebloods any wizard or witch born from a witch and a wizard, regardless of the parents blood status?
Example: Would Harry be considered a halfblood because his mother was Muggle-born? Or is he a pureblood because his parents were both magical? How about his kids?
