Magbob is an ancient term for a wizard of Muggle descent, meant to be a term of endearment. The term was popular prior to the formation of the International Statute of Wizarding Secrecy in 1692, in a period which most wizards considered Muggle-borns to be more gifted than wizards of purely magical blood. Following the circumstances that led to the Statute of Secrecy, wizards began to seriously distrust Muggles, pure-blood supremacy became widespread and the term fell out of favour.
- Though there is dispute over the origins of the term, "Magbob" is mostly like a portmanteau of "magic" and "bob", thus implying that a Magbob's magic "bobbed up" out of nowhere.
- The word "Magic" came up in late Middle English – its roots introduced in England only after the Norman Invasion in 1066, around 73 years after the founding of Hogwarts – due to which Magbob might from the Old French ' magique ' and the 14th Century sense of Bob - 'moving with a jerky motion.'
- The word could just as well be a portmanteau formed in the 1540s, when both, the modern sense of 'Magic' and 'Bob' were firmly formed. But since the word is supposedly coeval with Salazar Slytherin, this seems unlikely.
