The kanji 冗冗 is a 形声文字 (keisei moji), which means a phono-semantic compound character. This means it combines a semantic component (meaning) and a phonetic component (sound). The semantic component is likely the radical 亠 (たけかんむり, takekanmuri), which often relates to covering or something above. The phonetic component is 几 (き, ki), which provides the sound element. The combination implies something "above" or "extra" and gives the meaning of excess or superfluity.
