usage
Copperfield Literature
Created from the English words copper and field by the author Charles Dickens, who used it for the title character in his novel David Copperfield (1850).
Flintstone Popular Culture
From the English words flint and stone, created by Hanna-Barbera Productions for the caveman family (Fred, Wilma and Pebbles) in their animated television show The Flintstones, which ran from 1960 to 1966.
Karamazov Literature
Created by Russian author Fyodor Dostoyevsky for his novel The Brothers Karamazov (1879), about three brothers and their murdered father. Dostoyevsky may have based it on Tartar/Turkic кара (kara) meaning "black" and Russian мазать (mazat) meaning "stain". The connection to black is implied in the novel when one of the brothers is accidentally addressed as Mr. Черномазов (Chernomazov), as if based on Russian чёрный meaning "black".
McFly Popular Culture
Invented name, using the prefix Mc-, from Irish mac "son", and the English word fly. This name was created for the time-travelling hero Marty McFly of the Back to the Future movie series, beginning 1985.
Nickleby Literature
Created by Charles Dickens for the title character in his novel Nicholas Nickleby (1839). He probably based it on Nicol, a medieval vernacular form of Nicholas, with the common English place name suffix -by, which is derived from Old Norse býr meaning "farm, settlement".
Poppins Literature
Used by P. L. Travers for the magical nanny in her Mary Poppins series of books, first published in 1934. It is not known how Travers devised the name. She may have had the English words pop or poppet (meaning "young woman") in mind.
Quixote Literature
Created by the Spanish author Miguel de Cervantes for the main character in his novel Don Quixote (1605), about a nobleman who goes mad after reading too many heroic romances and decides to become a wandering knight under the name Don Quixote. His real name in part one of the book is conjectured to be Quixada or Quesada, though in part two (published 10 years after part one) it is revealed as Alonso Quixano. The Spanish suffix -ote means "large".
Scrooge Literature
Created by Charles Dickens for the central character in his short novel A Christmas Carol (1843). He probably based it on the rare English word scrouge meaning "to squeeze". In the book Ebenezer Scrooge is a miserly old man who is visited by three spirits who show him visions of his past, present and future. Since the book's publication, scrooge has been used as a word to mean "miser, misanthrope".
Skywalker Popular Culture
From the English words sky and walker, created by George Lucas as the surname for several characters in his Star Wars movie series, notably the hero Luke Skywalker from the original trilogy (beginning 1977). Early drafts of the script had the name as Starkiller.
Targaryen Literature
Created by author George R. R. Martin for his series A Song of Ice and Fire, published beginning 1996, and the television adaptation Game of Thrones (2011-2019). The Targaryens were the rulers of Westeros for almost 300 years until shortly before the beginning of the first novel. The name is presumably from the Valyrian language, though Martin provides no explanation of the meaning.
Valjean Literature
Created by Victor Hugo for Jean Valjean, the hero of his novel Les Misérables (1862). The novel explains that his father, also named Jean, received the nickname Valjean or Vlajean from a contraction of French voilá Jean meaning "here's Jean".
