Context: A regnal name, or reign name, is a name used by some monarchs and popes during their reigns, and used subsequently to refer to them. The term is simply the adjective "regnal", of or relating to a reign, monarch, or kingdom, modifying "name". Since ancient times, monarchs have frequently, but not always, chosen to use a different name from their original name when they accede to the monarchy.
The regnal name is usually followed by a regnal number (ordinal), usually written as a Roman numeral (VI rather than 6), to provide a unique identification for that monarch among other monarchs of that realm. In some cases, the monarch has more than one regnal name, but the regnal number is based on only one of those names, for example Charles X Gustav of Sweden, George Tupou V of Tonga. If a monarch reigns in more than one realm, he or she may carry different ordinals in each one, as they are each assigned chronologically, and some realms may have had different numbers of rulers of the same regnal name previously. For example, the same person was both King James I of England (along with Ireland) and King James VI of Scotland., A pen name ("nom de plume", or "literary double") is a pseudonym (or, in some cases, a variant form of a real name) adopted by an author and printed on the title page or by-line of his or her works in place of their "real" name. A pen name may be used to make the author's name more distinctive, to disguise his or her gender, to distance an author from some or all of his or her previous works, to protect the author from retribution for his or her writings, to combine more than one author into a single author, or for any of a number of reasons related to the marketing or aesthetic presentation of the work. The author's name may be known only to the publisher, or may come to be common knowledge., A stage name, also called a screen name, is a pseudonym used by performers and entertainers such as actors, comedians, and musicians., A name is a term used for identification. Names can identify a class or category of things, or a single thing, either uniquely, or within a given context. A personal name identifies, not necessarily uniquely, a "specific" individual human. The name of a specific entity is sometimes called a proper name (although that term has a philosophical meaning also) and is, when consisting of only one word, a proper noun. Other nouns are sometimes called "common names" or (obsolete) "general names". A name can be given to a person, place, or thing; for example, parents can give their child a name or a scientist can give an element a name., A pseudonym (and ) 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., Anthony Peter "Tony" Hatch (born 30 June 1939), also credited as Fred Nightingale and Mark Anthony, is an English composer for musical theatre and television. He is also a noted songwriter, pianist, arranger and producer., A ring name is a stage name used by a professional wrestler, martial artist, or a boxer. While some ring names may have a fictitious first name and surname, others may simply be a nickname from the moves that they do or their talents in the ring., An anagram is direct word switch or word play, the result of rearranging the letters of a word or phrase to produce a new word or phrase, using all the original letters exactly once; for example, the word anagram can be rearranged into nag-a-ram. Someone who creates anagrams may be called an "anagrammatist". The original word or phrase is known as the "subject" of the anagram. Anagrams are often used as a form of mnemonic device as well., A nickname is a substitute for the proper name of a familiar person, place, or thing, for affection or ridicule., A monarch is the sovereign head of state in a monarchy. A monarch may exercise the highest authority and power in the state, or others may wield that power on behalf of the monarch. Typically a monarch either personally inherits the lawful right to exercise the state's sovereign rights (often referred to as "the throne" or "the crown") or is selected by an established process from a family or cohort eligible to provide the nation's monarch. Alternatively, an individual may become monarch by conquest, acclamation or a combination of means. A monarch usually reigns for life or until abdication. , The pope (from "pappas", a child's word for "father") is the Bishop of Rome and, therefore, the leader of the worldwide Catholic Church. The primacy of the Roman bishop is largely derived from his role as the traditional successor to Saint Peter, to whom Jesus is supposed to have given the keys of Heaven and the powers of "binding and loosing", naming him as the "rock" upon which the church would be built. The current pope is Francis, who was elected on 13 March 2013, succeeding Benedict XVI., In modern popular fiction, a superhero (sometimes rendered super-hero or super hero) is a type of costumed heroic character who possesses supernatural or superhuman powers and who is dedicated to fighting crime, protecting the public, and usually battling supervillains. A female superhero is sometimes called a superheroine (also rendered super-heroine or super heroine). Fiction centered on such characters, especially in American comic books since the 1930s, is known as superhero fiction., `` Sugar and Spice '' is a 1963 song by Merseybeat band The Searchers written by Tony Hatch under the pseudonym Fred Nightingale .
