The word "劝说" (quànshuō) is a compound verb formed through the combination of two complementary characters: "劝" (quàn), which means to advise, urge, or encourage, and "说" (shuō), which means to speak or explain. This structure follows a common pattern in Chinese where two semantically related characters are joined to create a more specific meaning. In this case, the compound signifies the act of persuading someone through verbal reasoning and encouraging advice, where "劝" provides the sense of exhortation and "说" emphasizes the verbal articulation, together forming the complete action of "to persuade."
