The word **祝愿** (zhùyuàn) is a compound formed by combining two synonymous characters, each contributing to the core meaning of expressing goodwill. The first character, **祝** (zhù), originally depicted a person praying before an altar and means "to pray for" or "to wish well." The second character, **愿** (yuàn), means "wish," "desire," or "hope." When paired, they create a harmonious and slightly more formal binomial expression that means "to wish" or "good wishes," where **祝** emphasizes the active expression of the wish and **愿** signifies the content of the wish itself.
