2. Breach, infraction, violation, transgression all denote in some way the breaking of a rule or law or the upsetting of a normal and desired state. Breach is used infrequently in reference to laws or rules, more often in connection with desirable conditions or states of affairs: a breach of the peace, of good manners, of courtesy. Infraction most often refers to clearly formulated rules or laws: an infraction of the criminal code, of university regulations, of a labor contract. Violation, a stronger term than either of the preceding two, often suggests intentional, even forceful or aggressive, refusal to obey the law or to respect the rights of others: repeated violations of parking regulations; a human rights violation. Transgression, with its root sense of “a stepping across (of a boundary of some sort),” applies to any behavior that exceeds the limits imposed by a law, especially a moral law, a commandment, or an order; it often implies sinful behavior: a serious transgression of social customs, of God's commandments.
