Violet looked through her book at some of the other number meanings. Really, a lot of them seemed to have something to do with Hogwarts, but none were quite all of it. One was beginnings, Five was change and transition, and Nine was endings and completion--those were all part of Hogwarts, but only part of the time. Three had elves and creativity and Four meant building, endurance and hard work--well, this castle was a building that had endured for centuries, and they certainly put in a lot of hard work. The one she like best, next to Seven, was Two, because it dealt with relationships and human magic. But...Seven meant magic, too, and Hogwarts was more than relationships. Seven seemed best, though it didn't quite have everything.

When she finally answered, she said "I think seven is probably the best number for Hogwarts, though I don't think it says everything about it. But...if you take the three numbers adding up to seven, they altogether say something about Hogwarts--One means beginnings, and this is the beginning of our life in the wizarding world; Four means endurance and stability, like Margaret said--and also hard work, which we do a lot of! And Two means relationships and collaborations, which are also an important part of Hogwarts. And together they all add up to seven!"
