Squib

A Squib is a non-magical person born to two magical parents. Squibs are rare and are looked upon with some degree of disdain by witches and wizards, particularly pure-bloods. Sometimes, lack of early magical ability is mistaken for lack of magical ability at all, which was the case with Neville Longbottom and Merope Gaunt, who were both thought by their relatives to be Squibs.
