noun — a fraud, malpractice; a drawback, harm
字源 FORM — what the parts do
廾義two hands raised, working at something
Two hands (廾) busy under 敝 bì, which gives the sound — exact, no drift. 敝 is cloth worn ragged from being struck; hands working at something already shabby work it crookedly — hence cheating and the harm that follows: 作弊、弊端、弊病. The same 敝 builds 幣、蔽.
