expounds

Expounds is the third-person singular present tense of the verb expound. It means to explain in detail, to set forth in a systematic and authoritative way. When someone expounds a position, theory, or argument, they offer a thorough interpretation rather than a brief summary.

Etymology: The verb derives from Latin exponere, to set forth, and entered English via Old French and Middle English. The sense evolved to include presenting a detailed explanation or interpretation of a topic.

Usage: Expounds is common in academic, philosophical, religious, and legal writing. Examples: “The philosopher expounds a theory of mind”; “The preacher expounds the sermon”; “The judge expounds the statute.” It often appears with objects such as a doctrine, a theory, or a system. Colloquial use includes “expound on” or “expound upon” a topic to indicate elaboration.

Nuance: The term carries a formal connotation and may suggest a structured or persuasive presentation. It is more forceful than a simple “explain” and is typically used when the speaker or writer aims to interpret or defend a position at length. Some editors note that “expound on” is common in modern usage, but prefer concise alternatives in certain contexts.

Related terms: Explication refers to a detailed analysis or interpretation; exposition denotes a broad explanation or account. Elucidation and elaboration are nearby concepts. A person who expounds is often called an expositor, and an expounding work is an exposition or explanatory treatise.
