Mononymous person

A mononymous person is an individual who is known and addressed by a mononym, or "single name". In some cases, that name has been selected by the individual, who may have originally been given a polynym ("multiple name"). In other cases, it has been determined by the custom of the country or by some interested segment. In the case of historical figures, it may be the only one of the individual's names that has survived and is still known today.
