The Chinese word "卧室" (bedroom) is formed by combining two meaningful characters into a single conceptual unit: "卧" (wò), which means to lie down or recline, and "室" (shì), which means room or chamber. The formation is purely ideographic and semantic, where the first character describes the primary action ("lying down") and the second character defines the type of space ("room"). Together, they create a direct, compound pictogram of "a room for lying down", visually and conceptually representing the specific function of the space as a place for sleep and rest.
