What type of writing is primarily focused on informing or explaining?

Expository writing is primarily focused on informing or explaining a particular subject or concept to the reader. It presents facts, provides clear explanations, and often includes examples to support the information being conveyed. This type of writing is characterized by a logical organization of ideas and can include various formats such as essays, textbooks, and articles. The primary goal is to enhance the reader's understanding by presenting information in a straightforward manner without personal bias or emotional influences, which distinguishes it from other forms of writing like narrative or persuasive writing.
