Other forms: boarding schools
A boarding school is a private school where students live. Hogwarts School of Witchcraft and Wizardry is the fictional boarding school that Harry Potter goes to in the book series. Most are not that exciting.
If a place offers you room and board, you can eat your meals there and stay overnight. A boarding school does just that — it’s like a regular private school during the day but students don’t go home in the afternoon, they stay. It's similar to how many students go away to college and live in a dormitory, but it happens before college. Some boarding schools are religious or have another philosophy parents wish their children to learn.
