It's a literary term that refers to the process of revealing background information about the story, characters, setting, and other important elements.
Here's how it works:
* Exposition is a technique used in writing to deliver information to the reader.
* Parts of speech are grammatical categories of words (like noun, verb, adjective, etc.).
Therefore, "exposition" doesn't fit into any specific part of speech.
However, the words used to convey exposition can belong to various parts of speech:
* Nouns: "The author provided ample exposition in the first chapter."
* Verbs: "The character's backstory was expertly expounded upon."
* Adjectives: "The novel's expository passages were well-written."
