The kanji 剰剰 fundamentally conveys the idea of "surplus," "excess," or "remainder." It signifies something that is left over, more than what is needed, or the part of a quantity that is not evenly divisible.

The kanji 剰剰 is a 形声文字 (keisei moji), a phono-semantic compound. The phonetic component is 乗 (jō, meaning "to ride," but used here for sound), and the semantic component is 刀 (katana, meaning "sword") or 刂 (a variant of 刀), which refers to "cut" or "divide". The original meaning may have related to dividing something and seeing what remains. Over time, the meaning shifted to generally refer to the surplus or remainder after a division.
