As Zhenya looked around and noticed that others were answering more, she decided to try to put more information in. She raised her hand, "Professor, maybe it's silly, but it could be helpful for students to know that not every spell is classified as a charm, like I once thought! There are many other kinds of spells - seven. They are used in every day magic, and possibly - well I think probably, used more than the other kinds, especially Transfiguration. And I think people get a Charm and Transfiguration spells confused, but Transfiguration alters the object itself, whereas Charms alter the properties - what it does," she explained.
