The Chinese word **长途** (chángtú), meaning "long-distance," is a **compound word** formed through the morphological process of **combination**, where two independent, meaningful characters (morphemes) are joined to create a new semantic unit. The first character, **长** (cháng), means "long" in terms of length or duration, and the second, **途** (tú), means "road," "way," or "journey." When combined, their meanings fuse conceptually to denote "a long road" or "a long journey," which has been extended metaphorically to describe anything involving a great distance, such as long-distance travel (长途旅行), phone calls (长途电话), or transportation (长途汽车). This formation is typical in Chinese, where compounding is a primary method for creating precise vocabulary by logically combining existing semantic elements.
