Is expository and explanatory the same thing in writing?

Expository and explanatory writing are closely related but not identical. Expository writing aims to inform or explain a topic by presenting facts, data, or ideas clearly and logically. In contrast, explanatory writing focuses specifically on clarifying a concept or process, often providing insights or interpretations to help the reader understand it better. While both types involve elucidation, expository writing encompasses a broader range of informative purposes.
