The kanji 濫 is a phono-semantic compound (形声文字; keisei moji). It is composed of the radical 水 (みず), meaning "water," on the left side, indicating its association with overflowing or spreading. The right side is 監 (かん), which originally represented "to oversee" or "supervise." Therefore, 濫 originally implied a situation where water overflows its bounds, and by extension, anything that oversteps its limits.
