You're probably familiar with unruly, meaning "not readily controlled or disciplined." Have you ever wondered, "Is there a 'ruly' too?" If so, did it seem to you that such a word should exist? A little over 150 years ago, someone apparently followed that same thought process, creating "ruly" by dropping the prefix from "unruly." Whoever did so probably thought the coinage was a new one, but that's not quite the case. There had once been another "ruly" with much the same meaning as the modern term, but it had been out of use for over 200 years. Ultimately, "ruly" and "unruly" come from "reuly," a Middle English word meaning "disciplined." "Reuly" in turn comes from Middle English "reule," a predecessor of "rule."
