The Chinese word 堵车 (dǔchē), meaning "traffic jam", is a compound noun formed through semantic combination. It consists of the character 堵 (dǔ), which means "to block", "to stop up", or "to congest", and the character 车 (chē), which means "vehicle" or "car". When combined, the two characters create a vivid and logical concept: the blocking of vehicles, which directly and efficiently conveys the state of immobilized traffic on a road. This is a standard method of word formation in Chinese where two meaningful characters are joined to describe a new, specific phenomenon.
