The word **右侧 (yòucè)**, meaning "right side," is a standard Mandarin compound formed by combining two meaningful characters: **右 (yòu)**, which means "right" (as in direction), and **侧 (cè)**, which means "side" or "flank." This structure follows the common Chinese word-formation pattern of **modifier + head noun**, where "右" acts as an adjective specifying which side, and "侧" serves as the core noun. Together, they create a precise spatial term that is semantically transparent and more formal than the simpler, single-character synonym **右 (yòu)**.
