When you love a book series with all your heart, you know that not a lot of time passes between when you finish reading it to when you start reading it again from the top. Even if you know these books by heart, even if you can tell exactly what happens in each chapter just by the name of it, even if no plot twist surprises you anymore, you still enjoy reading these books each and every time. They still warm your heart just as they did at the very first time you opened each book.

What we love about awesome books like these, is that there are always new facts and hidden gems to discover. A great series is one that never stops revealing new details, even if it's just from how a certain name is written, or a number you never realized had a hidden significance.

When it comes to Harry Potter, we feel like there are always new things to discover, and new worlds to explore, and Potterheads around the world feel the same. Down below are 20+ hidden facts and pieces of information you may not have yet picked up, so keep scrolling to enjoy them, and share how many you already knew in the comments below!

    What clever thing in the Wizarding World did it take you too long to put together?

    This morning on my commute I realized for the first time that Slytherin is spelled with a "y" so that it begins with “Sly”. I am unsure how I never put that together before. Wondering if others have had experience like mine that made them go, "Of course!"

    transit41 Slytherin It's not too long, but on my re-read of the series after finishing the seventh book, I realized that: on text, Harry suspected that the broken pieces of Hagrid's wand was
