The Chinese word "太阳系" (tàiyángxì), meaning "solar system," is a straightforward compound noun formed by combining "太阳" (tàiyáng), which means "sun," with the morpheme "系" (xì), which means "system" or "series." The structure follows a common modifier-head pattern in Chinese, where "太阳" (sun) acts as the modifying element specifying the type of system, and "系" (system) serves as the head noun, indicating the core concept. Thus, the term literally translates to "sun system," directly and logically describing the astronomical system centered around our Sun.
