Muggle-born
Those born to Muggle families but who are skilled with magic are referred to as Muggle-borns. The child of two Muggles is considered a Muggle-born. In wizarding Britain, they are allowed to attend Hogwarts School of Witchcraft and Wizardry, although some other schools only admit students with wizarding heritage. Salazar Slytherin 
fell out of favour with the other Founders of Hogwarts because he wanted to limit attendance on the same grounds.
Those with prejudice against Muggles and their families often refer to such wizards as "Mudbloods," a highly offensive term implying that the individual has dirty and inferior blood. Those who discriminate against Muggle-borns believe that they do not deserve magic and should be excluded from the wizarding world, in spite of the fact that Muggle-borns are just as magically talented as those of other blood statuses.
