What is the meaning of the term that signifies making something clear by explanation?

The term that signifies making something clear by explanation is "elucidate." When one elucidates a concept, they are not only providing clarity but also enhancing understanding by making the subject more comprehensible through detailed explanation or illustration. This involves shedding light on complex ideas, often making them accessible to a wider audience.

"Clarify" is indeed similar in that it also seeks to make something clear, but it doesn't necessarily carry the depth of explanation that "elucidate" does. "Define" refers more to stating the meaning of a term or concept in precise terms, which is narrower than elaborating on it. "Outline" typically involves providing a general description or summary of a topic rather than deeply explaining it. Thus, "elucidate" is the most appropriate choice for conveying the idea of making something clear through detailed explanation.
