Background / Comments
You probably guessed the correct meaning if you thought of “unruly”. In fact, “unruly” is the older word, and our word is what is called a “back-formation”. Our word came from the Middle English word reuly (disciplined), which came from the Middle English word reule, from which we get “rule”.
