Fable
Fable is a literary genre: the succinct fictional story, in prose or verse, that attribute animals, legendary creatures, plants, inanimate objects, or forces of family that are anthropomorphized, as well as that illustrates or leads to a specific moral deterrent example a "moral", which may at the end be added explicitly as a concise maxim or saying.
A fable differs from a parable in that the latter excludes animals, plants, inanimate objects, together with forces of kind as actors that assume speech or other powers of humankind.
Usage has not always been so clearly distinguished. In the King James Version of the New Testament, "μῦθος" "mythos" was rendered by the translators as "fable" in the First Epistle to Timothy, the Second Epistle to Timothy, the Epistle to Titus and the First Epistle of Peter.
A adult who writes fables is a fabulist.
