Did You Know?

Pseudonym, has its origins in the Greek word pseudōnymos, which means "bearing a false name." Greek speakers formed their word by combining pseud-, meaning "false," and onyma, meaning "name." French speakers adopted the Greek word as 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.
