The word "恭喜" is formed by combining two independent characters, each carrying its own meaning, to create a new, layered concept. The first character, "恭", conveys a sense of respect, reverence, or polite solemnity. The second, "喜", means joy, happiness, or auspiciousness. When paired, they do not simply add together; instead, the respectful formality of "恭" frames and delivers the joy of "喜", transforming the expression into a formal and polite offering of congratulations, as if presenting joy with deference. This formation encapsulates the act of respectfully sharing in or acknowledging another's good fortune.
