Exposition means a clear explanation or presentation of information. In writing, it usually refers to the background details that help readers understand the characters, setting, or situation.

In simple words

  • General meaning: an explanation or detailed description.
  • In stories: the part that gives necessary background information.
  • Also used for events: a public show or exhibition, like a trade exposition.

Example

  • “The first chapter gives exposition about the kingdom and its history.”

If you want, I can also explain the difference between exposition and description.
