You can create your own spells, you just need to assume to a world a meaning ( actually it is more complicated than that, but that's the base ). So if you want you can take any word that cames from your head and then you can transform it into magic! So, they used the words from Harry Potter create real magic with those words and then put them in the respective category of spells.
