The word 折断 (zhéduàn) is formed through a common Chinese morphological process called a verb-resultative compound, where the first character 折 (zhé), meaning "to bend" or "to fold", indicates the action, and the second character 断 (duàn), meaning "to break" or "to snap", specifies the resulting state of that action. Together, they combine to create a single word meaning "to break by bending" or "to snap off", where the action of bending leads directly to the outcome of breaking. This structure efficiently conveys both the process and its completed result in a concise, logical unit.
