The kanji 賀 is a phono-semantic compound (形声文字, けいせいもじ). The semantic part is 貝 (shell), which originally represented "valuables" or "gifts," symbolizing an offering or something of value to be given. The phonetic part is 加 (ka), which provides the sound and hints at the idea of "adding" or "increasing" the value, contributing to the sense of celebration and adding to the joy. The character, therefore, combines the idea of valuable gifts with the sound, leading to the meaning of "celebration" or "congratulations."
