Folklore (or lore) consists of legends, music, oral history, proverbs, jokes, popular beliefs, fairy tales and customs that are the traditions of a culture, subculture, or group. It is also the set of practices through which those expressive genres are shared. The study of folklore is sometimes called folkloristics. The word 'folklore' was first used by the English antiquarian William Thoms in a letter published in the London journal The Athenaeum in 1846. In usage, there is a continuum between folklore and mythology. Stith Thompson made a major attempt to index the motifs of both folklore and mythology, providing an outline into which new motifs can be placed, and scholars can keep track of all older motifs.
Folklore can be divided into four areas of study: artifact (such as voodoo dolls), describable and transmissible entity (oral tradition), culture, and behavior (rituals). These areas do not stand alone, however, as often a particular item or element may fit into more than one of these areas.
Theyyam (Malayalam: തെയ്യം) or Theyyattam or Thira is a popular Hindu ritual form of worship of North Malabar in Kerala state, India, predominant in the Kolathunadu area (consisting of present-day Kasargod, Kannur Districts, Mananthavady Taluk of Wayanad and Vadakara & Koyilandy Taluks of Kozhikode of Kerala state. As a living cult with several thousand-year-old traditions, rituals and customs, it embraces almost all the castes and classes of the Hindu religion in this region. The performers of Theyyam belong to the lower class community, and have an important position in Theyyam. This is unique, since only in Kerala, do both the upper-caste Brahmins and lower-caste tribals share an important position in a major form of worship. The term Theyyam is a corrupt form of Devam or God. People of these districts consider Theyyam itself as a God and they seek blessings from this Theyyam. A similar custom is followed in the Tulu Nadu region of neighbouring Karnataka known as Bhuta Kola
