Tips
usage
滥 appears in many set compounds: 滥用 (abuse/misuse), 泛滥 (to flood/run rampant), 滥竽充数 (to pass off as competent). It always carries a negative sense of 'too much' or 'without restraint.'
memory
氵(water) + 监 (oversee): when the water overseers fail, water overflows — 滥 means flooding and excess.
