Pseudonym has its origins in the Greek adjective pseudōnymos, which means “bearing a false name.” French speakers adopted the Greek word as the noun pseudonyme, and English speakers later modified the French word into pseudonym. Many celebrated authors have used pseudonyms. Samuel Clemens wrote under the pseudonym “Mark Twain,” Charles Lutwidge Dodgson assumed the pseudonym “Lewis Carroll,” and Mary Ann Evans used “George Eliot” as her pseudonym.
