The Chinese word 外衣 (wàiyī), meaning "outer garment" or "coat", is a compound noun formed through semantic combination. It is composed of two characters: 外 (wài), which means "outside" or "outer", and 衣 (yī), which means "clothing" or "garment". When combined, they create a new, specific meaning through a straightforward modifier-head structure, where "外" describes the type or location of the "衣", effectively specifying it as clothing worn on the outside of other clothes, such as a jacket, coat, or overcoat.
