A wrong (from Old English wrang – 'crooked') is an act that is illegal or immoral. Legal wrongs are usually quite clearly defined in the law of a state and/or jurisdiction. They can be divided into civil wrongs and crimes (or criminal offences) in common law countries, while civil law countries tend to have some additional categories, such as contraventions.
Moral wrong is an underlying concept for legal wrong. Some moral wrongs are punishable by law, for example, rape or murder. Other moral wrongs have nothing to do with law. On the other hand, some legal wrongs, such as many types of parking offences, could hardly be classified as moral wrongs.
