Related Words

Willful, headstrong, perverse, wayward refer to one who stubbornly insists upon doing as they please. Willful suggests a stubborn persistence in doing what one wishes, especially in opposition to those whose wishes or commands ought to be respected or obeyed: that willful child who disregarded his parents' advice. One who is headstrong is often foolishly, and sometimes violently, self-willed: reckless and headstrong youths. The perverse person is unreasonably or obstinately intractable or contrary, often with the express intention of being disagreeable: perverse out of sheer spite. Wayward in this sense has the connotation of rash wrongheadedness that gets one into trouble: a reform school for wayward teens.
