The Chinese word **座椅** (zuòyǐ) is a compound noun formed by combining two synonymous or closely related morphemes: **座** (zuò), which means "seat" or "place to sit," and **椅** (yǐ), which means "chair." This type of formation, where two elements with similar meanings are joined, is common in Chinese to create a more precise or formal term. Together, they specify the object as a "seating chair" or simply a formal "seat," with **座** emphasizing the function of sitting and **椅** specifying the furniture type, resulting in a word that is more concrete and specific than either component alone.
