The Chinese word **橱柜 (chúguì)** is a compound noun formed by combining two synonymous or closely related characters: **橱 (chú)**, which typically refers to a cabinet or closet (often with doors or shelves, like a kitchen cabinet), and **柜 (guì)**, which generally means a cupboard, cabinet, or chest. Together, they create a single, more specific term that emphasizes the idea of a storage unit with doors and shelves, most commonly understood in modern usage as a **"kitchen cabinet"** or a built-in wardrobe. This formation follows a common pattern in Chinese where two characters with similar meanings are joined to reinforce or specify a concept, resulting in a word whose meaning is more precise or nuanced than either character alone.
