Did you ever hear of the word Quidditch before you read the Harry Potter books? Or even muggle? No, you didn’t because author J.K. Rowling invented these words for her Harry Potter world. This is common for authors, who invent new words within their stories. J. R.R. Tolkien created the word tween, while Shakespeare created over several thousand new words, like bump, sanctimonious, gnarled and bloody.
These are only a few of the words that have been created by authors. 10 Words Invented by Authors, is another site that explores some more words that have been created by authors.
