Half-blood

Half-blood is the term commonly given to wizards and witches who had known Muggle or Muggle-born parents or grandparents.
It should be noted that any wizard or witch who is neither pure-blood nor Muggle-born is considered half-blood, even if they have two magical parents; they need not have exactly half-Muggle/half-wizard heritage.
Non-magical children born with at least one magical parent are considered Squibs by the wizarding community rather than Half-bloods or Muggles
