The Chinese word "胸罩" is formed by combining the character "胸", which means "chest" or "bosom", with "罩", which means "cover" or "shield". Together, they create a literal meaning of "chest cover", directly describing the item's function as a garment that covers the chest, specifically a bra. This compound word simply merges two meaningful components to convey both the body part involved and the action of covering it, resulting in a clear and intuitive term for the undergarment.
