The Chinese word 微波炉 (wēibōlú) for "microwave oven" is formed through a logical, descriptive compound process: the first two characters 微波 (wēibō) mean "microwave", directly translating the scientific term for the electromagnetic radiation used, and the final character 炉 (lú) means "oven" or "stove". Thus, the term is constructed semantically as "microwave" + "oven", creating a precise and transparent name for the appliance based entirely on its core operating principle.
