The Chinese word 皱纹 (zhòuwén), meaning "wrinkle", is a compound noun formed through semantic combination. The first character, 皱 (zhòu), means "to wrinkle" or "to crease", and functions as a verb or stative verb indicating the action or state of becoming furrowed. The second character, 纹 (wén), means "line", "grain", or "pattern", and acts as a noun. When combined, 皱 modifies 纹 to specify the type of line: essentially, "a line formed by wrinkling" or "a crease pattern". This structure follows a common modifier-head (or verb-object implicit) pattern in Chinese, where the first element describes the second, creating a precise and vivid term for a skin fold or a crease in a material.
