An exposition is an explanation or description of something, usually in detail. It's often used in writing, especially in non-fiction books.
When you hear about someone giving an exposition on their research project, they're probably going to talk for a while and tell you all about it. Expositions are also common in movies and documentaries, where experts explain scientific or historical concepts in a way that's easy to understand. Even if you're watching a film just for fun, there might be an exposition scene where the main character explains their thoughts and feelings in depth. Sometimes, expositions can feel a bit long-winded, but they help us get into the story or learn something new.
