How to use expound
Expound is used when someone explains or presents ideas in detail, often at considerable length. It has a more formal, somewhat elevated tone than simple 'explain' and suggests thorough, systematic treatment. The speaker often expounds on or upon a subject, especially their own theories, beliefs, or interpretations. It carries a mild suggestion that the explanation may be lengthy or detailed rather than concise.

A common mistake
Learners sometimes confuse expound with compound or expand; expound specifically means to explain at length, not to combine or enlarge.
