Young adult fantasy

Fantasy is a genre of speculative fiction which involves themes of the supernatural, magic, and imaginary worlds and creatures.

Its roots are in oral traditions, which became fantasy literature and drama. From the twentieth century, it has expanded further into various media, including film, television, graphic novels, manga, animations, and video games.

The expression fantastic literature is also often used to refer to this genre by the Anglophone literary critics. An archaic spelling for the term is phantasy.
