The word "富贵" is formed by combining two pictophonetic characters: "富" meaning wealth, constructed with the radical "宀" (roof) representing household and the phonetic component "畐" implying abundance; and "贵" meaning nobility, constructed with the radical "貝" (shell/currency) representing value and the phonetic component "臾" contributing to its sense of high status. Together, they create a compound word denoting material prosperity and social esteem.
