About
幄 is a phono-semantic compound: the semantic radical 巾 (cloth) indicates its material, while the phonetic component 屋 (house, room) suggests its function as a shelter. Originally, it referred specifically to a cloth tent or marquee, often used for military or royal encampments. The character thus designates a temporary, cloth-based structure, commonly appearing in classical literature to describe a general's command post or a ceremonial pavilion.
