[Middle English breche, from Old English brēc; see bhreg- in the Appendix of Indo-European roots.] Synonyms: breach, infraction, violation, transgression, trespass, infringement These nouns denote an act or instance of breaking a law or regulation or of failing to fulfill a duty, obligation, or promise. Breach and infraction are the least specific; when applied to lawbreaking they may imply a relatively minor offense, but they are also widely used in nonlegal contexts: Revealing the secret would be a breach of trust. Their behavior amounted to an infraction of the unwritten social code. Violation generally applies to the breaking of an explicit law or rule (a traffic violation; a violation of international law); it can also imply a failing to follow a moral or ethical standard: a violation of human rights; a violation of one's privacy. Transgression and trespass most often apply to divine or moral law: "She had said that the transgression was all the more shocking because the official was charged with enforcing federal laws against sexual harassment" (Jane Mayer and Jill Abramson). "The act of torture is such an extreme trespass against the laws of war that it may seem beside the point to wonder whether any other forms of wrongdoing have been carried out" (Elaine Scarry). Infringement is most frequently used to denote encroachment on another's rights: "Necessity is the plea for every infringement of human freedom" (William Pitt the Younger).
