The Chinese word **天鹅** (tiān'é), meaning "swan," is a compound noun formed through semantic combination, where the first character **天** (tiān) meaning "sky" or "heaven" descriptively modifies the second character **鹅** (é) meaning "goose." This constructs the literal concept of a "sky-goose," a poetic and visual description that captures the bird's graceful, lofty flight and its elevated, almost ethereal appearance compared to a common goose, effectively creating a new, specific meaning through this metaphorical juxtaposition.
