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.
