Examples of Muggle in a sentence
"We joked that my dad was a muggle in the kitchen because everything turned out burnt."
"I'm quite a muggle when it comes to any sport."
It's a silly little word created by J.K. Rowling in the Harry Potter series. Muggle simply means someone without magical skill. It proved to be so useful that it was added to the dictionary to describe somoeone without skill, not restricted to the wizarding world.
Did you Know?
For a relatively recent addition to the world of literary classics ("Harry Potter and the Sorcerer's Stone" was published in 1997), the vocabulary of Hogwarts has been quickly adopted. In addition to muggle, you're likely to hear wizarding lingo such as Quidditch, Voldemort, galleon, and patronus cast about like spells.
