Myth, legend, folktale — what is the difference?

Four words, four relationships

The words are not four names for the same thing, and they are not a ranking from serious to childish. Each one describes a different relationship between a story and the people who tell it.

Myth explains. It accounts for how something came to be — the world, the moon, death, a people — and it is set outside ordinary history, in a time before the present arrangement of things, among gods, first beings or forces.

Legend claims. It is set in the human world, usually at a named place and often a stated time, and it is told as a thing that happened, whether or not the teller believes it. "There is a crossing outside town where a woman is heard crying" is a legend. It can be checked, in principle, and that is the point.

Folktale entertains and instructs. It makes no claim about history at all. Nobody asks where or when it happened, because the question is irrelevant to the kind of story it is.

Fairy tale is a subset of folktale with a recognisable shape: a protagonist leaves home, is tested, is helped by someone met on the road, and the story closes.

The test that actually works

Forget the content and ask what the teller is doing.

Question	Myth	Legend	Folktale
Is it set in ordinary history?	No	Yes	Doesn't matter
Does it explain how something came to be?	Yes	Rarely	No
Is there a named place?	Rarely	Usually	No
Is it told as true?	As sacred or foundational	As something that happened	No claim

A story's category can change without a word of it changing, simply by being told differently. That is not the categories failing. It is them measuring the right thing.

Four worked examples

Bakunawa swallowing the moon — a myth. It explains an eclipse. It happens in no particular year, in no particular village, and it accounts for a feature of the world that everybody can see. The accompanying practice — going outside and making noise — is what people do about the explanation.

La Llorona — a legend. She is at a specific river, a specific canal, the crossing outside this town. People will tell you which one. The story is told as something that happened to somebody, and it attaches to places that exist. Nothing about the world is explained; a warning is issued.

Baba Yaga — a folktale figure. She appears inside wonder tales, with no place and no date, and nobody asks where her hut stands. The tales she appears in are the fairy-tale shape: a child or a youngest daughter leaves home, meets her, is tested, and either survives or does not according to how they behave.

Camazotz — neither, exactly. The bats of the Bat House belong to a long narrative about the ancestors of a people, written down in the sixteenth century. That puts the Popol Vuh closer to the mythic end — it is foundational and it explains — but the Bat House episode itself is an adventure within it. A single text can hold both.

Where the line fails

Three cases that are worth knowing precisely because the categories do not survive them cleanly.

The creature that moves between kinds. The aswang appears in explanations, in told-as-true accounts about named neighbours, and in entertainment. It is the same creature doing three different jobs.

The legend with a myth's ancestry. La Llorona's modern form is a legend, but the image behind it — a woman heard weeping at night — comes to us from a sixteenth-century account of omens before the fall of a city. The ancestry is mythic; the living story is not.

The folktale that people act on. A story told for entertainment can still carry a rule — do not go into the forest alone, do not go near the water in June — and the people who laugh at it still follow the rule. The category describes the telling, not the belief.

Why the words exist at all

They were made by folklorists in the nineteenth and twentieth centuries to sort an enormous quantity of collected material, and they work best as questions rather than labels: What does this story claim? Where is it set? What would its teller say if you asked whether it was true?

Asked that way, the terms do real work. Used as boxes, they produce arguments about whether something "really" is a myth, which is the least interesting question available about any story.
