There are all sorts of words and phrases from pop culture that have crossed over into the wider vernacular. Some are extremely well known. Others are less so, but still incredibly fun and useful once you know them. These are a few of my favorites.
Watsonian and Doylist
Definition: From the perspective of a person in a fictional world (Watsonian) or from the perspective of an author or reader (Doylist). Useful in discussion of a fiction to clarify if you are talking about “in universe” explanations for something that happened or the “behind the scenes” version of events.
Etymology: The terms have their origins in Sir Arthur Conan Doyle’s Sherlock Holmes stories and refer to the two different people who could be said to have authored those works. Dr. John Watson is a fictional character in the same world as Holmes. To him, Holmes is a real person capable of acting and thinking on his own. Sir Arthur Conan Doyle is a real author who sees Holmes as a fictional character whose actions are dictated by a writer and the outside pressures that influence the writer.
