The wizarding world of J.K.Rowling's Harry Potter books are full of terminology, creatures, and objects entirely unique to this universe. This whole new world for readers to explore, along with relatable characters and a great sense of humor (for example, Hogwart's motto is Draco Dormiens Nunquam Titillandus, meaning "Never Tickle a Sleeping Dragon") makes it a wonderful read for both children and adults. The series has captivated entire generations with years of reading and movie-watching and continues to be adored by fans but old and new.

In the first book, Harry Potter and the Sorcerer's Stone (also known as Harry Potter and the Philosopher's Stone) readers are introduced to the infamous Harry Potter. Raised by muggles after the death of his parents, Harry is unaware of his wizard background until his eleventh birthday, when he receives a mysterious letter inviting him to attend the Hogwarts School of Witchcraft and Wizardry. His experiences enable him to step into an amazing world full of magic, learn more about his past, and have his second encounter with Lord Voldemort (the first being when he was a baby) as he seeks the Sorcerer's Stone.

The second book, Harry Potter and the Chamber of Secrets, takes place in Harry's second year at Hogwarts. A new mystery arises as students are turned into stone for reasons no one understands, although many rumors float through Hogwarts. Could it be Harry Potter himself, with his new-found ability to speak Parseltongue? Or could it be Malfoy, his nemesis that has only recently provided Harry with his first taste of anti-Muggle racism in the wizarding world?

The next book in the series is Harry Potter and the Prisoner of Azkaban. Sirius Black has escaped from Azkaban, Hermione keeps disappearing, death omens seem to be everywhere, and Dementors have come to guard Hogwarts. All of these combined have Harry fearing for his life, even with his new Firebolt, Marauder's Map, and his loyal friends by his side because, on top of everything he has to worry about, he realizes there is a traitor hidden at Hogwarts.

The fourth book is entitled Harry Potter and the Goblet of Fire. For the first time in a century, the deadly Triwizard Tournament has come to Hogwarts, along with two rivals from two other magic schools in other countries. Everything goes according to plan, with Cedric Diggory chosen as Hogwarts' champion, until the shocking discovery that someone cheated the system and Harry Potter is named as yet another champion, which means someone wants him dead.

Book five is Harry Potter and the Order of the Phoenix, introduces reader to a secret society that works to fight against the Dark Lord's followers and protect targets like Harry Potter. This society is, of course, the Order of the Phoenix. Discredited by the Daily Prophet, Harry must deal with a new-found hatred by classmates, while haunted by dreams of a mysterious door at the end of a hallway. He founds Dumbledor's Army and helps train students to defend themselves against the Dark Arts.

Harry Potter and the Half-Blood Prince is the next book. Book six explores the story of Tom Riddle as Harry and Dumbledor work together to uncover Voldemort's past. Little do they realize the consequences of their searches as Harry's future, as well as that of Hogwarts, is suddenly put at risk.

The final book in the series, Harry Potter and the Deathly Hallows, brings readers to the final moment that all of the books have been leading up to: the battle between Voldemort and Harry Potter. After suffering great loss and heartache, is Harry up to the challenge with a newly revived Dark Lord and his army of Death Eaters?

Wow.........this is so amazing! I am a Harry Potter Fan and I totally love the list of categories and terms that you have provided. When J.K. Rowling released her first books I bought the collector set because I knew her Harry Potter series was going to be a huge hit. This was great! Thanks for sharing. (Voted Up) -Rose

I've been watching the reruns of the movies on TV and I'd forgotten how good they were! One of my aims this summer is to reread the series and immerse myself again in this other world created so skilfully by J.K. Rowling. If I manage to do it, I think your article would be the perfect companion. It's so informative and interesting, written in a very accessible way. So when the metamorphmagu is casting a relashio spell, I'll at least know who they are!
