The type of romance considered here is mainly the genre of novel defined by the novelist Walter Scott as "a fictitious narrative in prose or verse; the interest of which turns upon marvellous and uncommon incidents", in contrast to mainstream novels which realistically depict the state of a society. These works frequently, but not exclusively, take the form of the historical novel. Scott's novels are also frequently described as historical romances, and Northrop Frye suggested "the general principle that most 'historical novels' are romances". Scott describes romance as a "kindred term", and many European languages do not distinguish between romance and novel: "a novel is le roman, der Roman, il romanzo".
There is second type of romance where the primary focus is on "romance", in the sense of love and marriage. Jane Austen wrote this type of romance. A strong love interest is also found in a very different type of literary fiction romance such as Wuthering Heights and Jane Eyre, works that correspond more to Scott's definition of the romance genre than Austen's novels do. Literary fiction, in the book-trade, are novels that are regarded as having literary merit and can employ a variety of subgenres, including the love romance novel, the historical novel, the adventure novel, and scientific romance. Works of nautical fiction can also be romances, as the genre often overlaps with historical romance, adventure fiction, and fantasy stories. The Oxford English Dictionary, suggests that the term "romance", as applied to literary fiction, is "now chiefly archaic and historical," and is now mainly used to refer to genre fiction love romances.
The terms "romance novel" and "historical romance" are ambiguous, because the words "romance", and "romantic", can have different meanings: for example, romance can refer to romantic love, or "the character or quality that makes something appeal strongly to the imagination, and sets it apart from the mundane; an air, feeling, or sense of wonder, mystery, and remoteness from everyday life; redolence or suggestion of, or association with, adventure, heroism, chivalry, etc.
