The Chinese word **款式** (kuǎnshì), meaning "style," "design," or "pattern," is a **compound word formed by combining two semantically related characters**. The first character, **款** (kuǎn), originally referred to an inscription or a section of text, and by extension, it came to signify the distinctive "features" or "specifications" of something. The second character, **式** (shì), directly means "pattern," "formula," or "type." When paired together, these characters create a **synergistic or coordinative compound** where both elements contribute to a unified meaning that is more specific than either alone, essentially denoting the "form and pattern" or the particular "manner and model" that defines the aesthetic or structural characteristics of an object, such as clothing or furniture.
