What does it mean to make an idea clearer through explanation?

The term that best describes the act of making an idea clearer through explanation is "clarify." To clarify means to make something less confusing and more comprehensible, allowing the audience to easily grasp the intended meaning. When you clarify an idea, you break it down into simpler terms, provide additional details, or eliminate ambiguity—effectively helping to ensure that your audience understands the concept you are discussing.

In contrast, while "illustrate" involves providing examples or visual aids to support understanding, it does not inherently entail making the idea clearer through explanation alone. "Reveal" suggests uncovering something hidden or not readily apparent, which is different from the process of making an idea clearer. "Convey" refers to the act of communicating an idea, which can involve clarity, but it does not specifically emphasize the aspect of enhancing understanding through explanation. Thus, "clarify" directly aligns with the goal of making an idea clearer.
