The Chinese word **饶舌** (ráoshé) is formed through the semantic combination of its two constituent characters: **饶** (ráo), which carries the meaning of "rich," "abundant," or more figuratively "excessive," and **舌** (shé), which literally means "tongue." Together, they create a vivid metaphorical compound meaning "excessive tongue," directly picturing an overactive tongue in motion. This imagery evolved to denote the act of talking too much or being unnecessarily talkative (verbally "abundant"), and by further extension, it is now the standard term for the musical genre "rap," which is characterized by fast, dense, and rhythmic speech. Thus, the formation moves from a literal anatomical metaphor to an abstract descriptive term and finally to a specific cultural label.
