What is a legend?

Legend

A legend is a traditional story or body of stories, usually of oral origin, that is handed down from generation to generation and popularly believed to have a historical basis. It can also be a story based more on fancy than on fact.

In other circles, it means an inscription - as on a coin
A legend (Latin, legenda, "things to be read") is a narrative of human actions that are perceived both by teller and listeners to take place within human history and to possess certain qualities that give the tale verisimilitude. Legend, for its active and passive participants, includes no happenings that are outside the realm of "possibility", defined by a highly flexible set of parameters, which may include miracles that are perceived as actually having happened, within the specific tradition of indoctrination where the legend arises, and within which it may be transformed over time, in order to keep it fresh and vital, and realistic.

In modern times a legend is somebody who revolutionizes a specific field or area. For instance Steve Jobs was a business legend who revolutionized 6 separate industries.
