Pseudonym

A pseudonym (UK pronunciation: /ˈsjuːdənɪm/ SYOO-də-nim and US pronunciation: /ˈsuːdənɪm/ SOO-də-nim) or alias is a name that a person or group assumes for a particular purpose, which can differ from their original or true name (orthonym). Pseudonyms include stage names and user names (both called screen names), ring names, pen names, nicknames, aliases, superhero identities and code names, gamer identifications, and regnal names of emperors, popes, and other monarchs. Historically, they have often taken the form of anagrams, Graecisms, and Latinisations, although there are many other methods of choosing a pseudonym.
