Examples of genres change
A subgenre is a subordinate within a genre. Two stories being the same genre can still sometimes differ in subgenre. For example, if a fantasy story has darker and more frightening elements of fantasy, it would belong in the subgenre of dark fantasy; whereas another fantasy story that features magic swords and wizards would belong to the subgenre of sword and sorcery.
