The word 镶黄旗 is formed by sequentially combining three characters: 镶, which in this context means "bordered" or "edged"; 黄, meaning "yellow"; and 旗, meaning "banner". Together, they directly compose the term for the "Bordered Yellow Banner", a specific division within the historical Eight Banners system, where 镶 modifies 黄 to indicate a variant of the yellow banner, and 旗 denotes the organizational unit.
