Myth and Urban Myth

For a word so often applied to events or stories from long, long ago, myth has a remarkably recent history in the English language. The earliest evidence for the word is from 1830, well after the time when the events themselves are thought to have occurred (though it should be noted that the related words mythology and mythic are hundreds of years older – still not as old as Achilles, but not young, either!). One application of myth, however – in the phrase urban myth – is quite new. Curiously, an urban myth does not usually have anything to do with the city: it is simply “a story about an unusual event or occurrence that many people believe is true but that is not true.” An example would be the tale that Elvis Presley is still alive after spending decades in a witness protection program. The phrase urban myth has been used to describe such hoaxes since at least 1971.
