The Chinese word **大堂 (dàtáng)** is formed through semantic compounding, where two independent characters—**大 (dà)**, meaning "big" or "grand," and **堂 (táng)**, meaning "hall" or "main room"—are combined to create a new term. This compound directly and logically fuses their individual meanings to denote a "grand hall" or "main lobby," such as the spacious entrance area of a hotel, bank, or other public building, illustrating a common Chinese word-formation process where the combined sense is a clear sum of its parts.
