The Chinese word **押韵** (yāyùn), meaning "to rhyme," is a compound verb formed through semantic combination: the first character **押** carries the sense of "to constrain" or "to press down," metaphorically implying the action of imposing a pattern or agreement, while the second character **韵** means "rhyme," "phonetic harmony," or "agreeing final sound." Together, they create the concept of "applying rhyme" or "matching sounds," where **押** denotes the active process of making words conform rhythmically, and **韵** specifies the domain of that action—the rhyming pattern itself, typically in poetry or song lyrics.
