Which term means to explain something in detail?

The term "expound" means to explain something in detail, often with clarity and thoroughness. It is commonly used in academic and formal contexts when someone is asked to elaborate on a concept, theory, or argument. When you expound on a topic, you lay out all the necessary components and nuances, thereby providing a comprehensive understanding for the audience.

While "describe," "elucidate," and "delineate" all involve explaining or clarifying a subject, they each have distinct connotations. "Describe" typically refers to giving an account of something, which may not be as detailed as expounding. "Elucidate" focuses on making something clear, often by providing additional information, but it doesn't necessarily imply depth. "Delineate" means to outline or represent something in detail but often in a more visual or structural sense rather than through expansive verbal explanation. Therefore, "expound" stands out as the term that explicitly emphasizes the act of providing a detailed and systematic explanation.
