The kanji 慢 is a phono-semantic compound (形声文字, けいせいもじ). The left side, 忄 (りっしんべん - りっしんべん), is a radical related to the heart or emotions. The right side, 曼 (まん - man), originally meant "long" or "slow." The combination suggests a heart (忄) that is "slow" or "drawn out" (曼) in its actions or feelings, leading to the meaning of slowness, or the related concepts of arrogance or complacency.
