A "Muggle" is a term used in the Harry Potter series by J.K. Rowling to describe a person who does not possess magical abilities. Muggles live in a world that is unaware of the existence of magic and magical beings. They typically lead ordinary lives, engaging in everyday activities without any knowledge of the wizarding world. In the context of the series, Muggles often encounter magical elements without realizing their significance. The term highlights the contrast between the magical community and the non-magical world, emphasizing the differences in lifestyle, knowledge, and experiences between wizards and Muggles.
