Scofflaw

skôflô

 Noun      Informal • North American

A person who flouts the law, especially by failing to comply
with a law that is difficult to enforce effectively.

1924, a wealthy Massachusetts Prohibitionist named Delcevare King sponsored a contest in which he asked participants to coin an appropriate word to mean "a lawless drinker." King sought a word that would cast violators of Prohibition laws in a light of shame. Two respondents came up independently with the winning word: scofflaw, formed by combining the verb scoff and the noun law. Henry Dale and Kate Butler, also of Massachusetts, split King’s $200 prize. Improbably, despite some early scoffing from language critics, scofflaw managed to pick up steam in English and expand to a meaning that went beyond its Prohibition roots, referring to one who violates any law, not just laws related to drinking.
