Difference among tall tales, legends, myths, fairy tales and fables

TALL TALEs humorously exaggerate facts with plausible story lines.

LEGENDs embellish and glorify historical facts or fiction passed down through generations.

MYTHs explain natural phenomena with supernatural beings or creators based on religion.

FAIRY TALEs usually conflict between clearly separated good and evil with magic and imaginary creatures.

FABLEs teach a moral with talking animals.
