**Unrulier** → It is formed from "un-" (meaning not) and "ruly" (from the Middle English *reuli*, meaning orderly or well-behaved) with the comparative suffix "-er" (indicating more). The word "unrulier" means more not orderly or more disobedient than something else.
Think of 'not' ('un-') being added to 'orderly' ('ruly') to describe something that is more disobedient or chaotic.
