expository

Think of an expository essay: it explains information clearly. The word "expository" describes something meant to explain or inform, like a textbook chapter, a documentary film, or a well-written news article. It is about presenting facts and ideas in a clear, organized way. If your friend asks you to "explain how photosynthesis works," you're being asked to give an expository explanation.

Expository writing is not trying to tell a story (that's narrative) or persuade you of something (that's argumentative). It simply shows what something is, how it works, or why it matters. You might find expository passages in nonfiction books, scientific reports, or even instructions for assembling furniture.

The word "expository" is related to "exposition," which means explanation or clear presentation. Something expository aims to explain a topic clearly and objectively. It presents information in a logical, organized way so the reader or listener can understand it.

You'll most often encounter "expository" when discussing writing or speech. An *expository essay*, for example, does not tell a story or mainly argue a point; instead, it explains a topic by giving facts, examples, definitions, and analysis. Think of an encyclopedia entry: that is strongly expository.

However, "expository" can also describe other forms of communication. A documentary film might use an *expository mode* to present information about a historical event or scientific phenomenon. A teacher giving a lecture may use an expository style. Even detailed instructions on how to build something can be expository in nature.

The key characteristic of anything expository is its focus on explanation. It values clarity, accuracy, and organization over storytelling or emotional appeal. While other kinds of writing may aim to entertain or persuade, expository communication mainly aims to explain and inform. So, if you are looking for facts, ideas, and understanding, you are looking for something expository.
