What is the difference between mores and law?

As nouns the difference between mores and law is that mores is a set of moral norms or customs derived from generally accepted practices rather than written laws while law is (uncountable) the body of rules and standards issued by a government, or to be applied by courts and similar authorities or law can be (obsolete) a tumulus of stones. As a interjection law is (dated) an exclamation of mild surprise; lawks.
