No one is certain about the origin of the idiom 'break the law,' however it is more than likely an ancient one. 'Break the law' is closely related to the 15th century term 'interrupt,' which originally meant 'to interfere with a legal right.' The word 'break' comes from the Old English brecan, and the word 'law' comes from Old English lagu. The closely related term 'lawbreaker' originated in the 15th century, while the term 'lawless' originated in the early 13th century.
