The Chinese word 豌豆 (wāndòu), meaning "pea," is a compound word formed through semantic combination. The second character, 豆 (dòu), is the core semantic component meaning "bean" or "legume." The first character, 豌 (wān), acts primarily as a phonetic indicator to specify the pronunciation while also carrying a vague associative meaning related to its curvature or the "bowl" (碗, wǎn) shape of a pea pod, though its main function is to distinguish this specific type of bean from others. Thus, the word is constructed by pairing a classifying character (豆) with a modifying character (豌) to create a precise, disambiguated term for a specific legume.
