The word "划痕" is a compound noun formed by combining the verb "划" (huá), meaning to scratch or scrape, with the noun "痕" (hén), meaning a mark or trace. This structure follows a common Chinese word-formation pattern where an action and its result are linked to create a new term; thus, "划痕" literally means "a scratch-mark" or "the mark left from scratching," succinctly describing the physical result of the action.
