The kanji 堂 is a 形声文字 (keisei moji), a phono-semantic compound. It combines a semantic component (meaning) with a phonetic component (sound). The left side is a radical, 宀 (うかんむり, ukanmuri), which represents a "roof" or "house." The right side is 唐 (とう, tō), which provides the sound element ドウ (dō). Thus, the character originally depicted a building under a roof, and evolved to represent a grand hall or important structure.
