Example: Publishing someone’s words as your own is a crime.

Synonym Usage

Crime, offense, sin agree in meaning a breaking of law. Crime usually means any serious violation of human laws: the crime of treason or robbery. Offense is used of an infraction of either human or divine law, and does not necessarily mean a serious one: an offense leading to a jail sentence; an offense against morals. Sin means a breaking of moral or divine law: the sins of greed and lust.

Etymology

Origin of crime

First recorded in 1200–50; Middle English, from Anglo-French, Old French, from Latin crīmin-, stem of crīmen “accusation, blame, charge,” akin to cernere “to decide, distinguish, separate,” literally, “to sift” ( cf. discern ( def. ))

Explanation

Something that's against the law is a crime. If your friend shoplifts clothes from a store, you'll be disappointed because you know that stealing is a serious crime. A crime is an illegal act that someone can be legally punished for, like damaging someone's property. You can also talk about crime more generally to describe something that's unfair, wrong, and difficult to fix, like the crime of art museums charging high admission prices, making it all but impossible for many families to afford to go often.
