The word "exposition" originates from Latin expositio, derived from exponere ("to put out, explain"). The morpheme ex- means "out," pos- (from ponere) means "to place," and -ition is a noun-forming suffix. Historically, it referred to the act of "laying out" information or objects for public view, evolving into its modern meanings of explanation (e.g., in writing) and exhibition (e.g., world fairs). The logic reflects a progression from physical placement ("placing out") to abstract presentation.
