Letter and spirit of the law

The letter of the law and the spirit of the law are two possible ways to regard rules or laws. To obey the letter of the law is to follow the literal reading of the words of the law, whereas following the spirit of the law is to follow the intention of why the law was enforced. Although it is usual to follow both the letter and the spirit, the two are commonly referenced when they are in opposition. "Law" originally referred to legislative statute,[citation needed] but in the idiom may refer to any kind of rule. Intentionally following the letter of the law but not the spirit may be accomplished through exploiting technicalities, loopholes, and ambiguous language.
