Myth is a genre of folklore or theology consisting primarily of narratives that play a fundamental role in a society, such as foundational tales or origin myths. For scholars, this is very different from the vernacular usage of the term "myth" that simply refers to something that is not true. Instead, the truth value of a myth is not a defining criterion.

Folklore is the body of expressive culture shared by a particular group of people, culture or subculture. This includes oral traditions such as tales, myths, legends, proverbs, poems, jokes, and other oral traditions. This also includes material culture, such as traditional building styles common to the group. Folklore also encompasses customary lore, taking actions for folk beliefs, and the forms and rituals of celebrations such as Christmas, weddings, folk dances, and initiation rites.
