“To elaborate” means to provide more detailed information or a fuller explanation about a subject. It is often used when someone requests additional clarity, examples, or step‑by‑step descriptions to better understand an idea, plan, or argument. The verb can describe both speaking and writing, such as elaborating on a theory in a paper or elaborating on feedback in a meeting. It may also refer to developing something further, like elaborating a concept into a complete proposal. The focus is on expanding, refining, and making information richer, clearer, and more precise for the audience.
