Synonyms:
disobedient, unmanageable, uncontrollable, stubborn, disorderly, riotous. Unruly, intractable, recalcitrant, refractory describe persons or things that resist management or control. Unruly suggests persistently disorderly behavior or character in persons or things: an unruly child, peevish and willful; wild, unruly hair. Intractable suggests in persons a determined resistance to all attempts to guide or direct them, in things a refusal to respond to attempts to shape, improve, or modify them: an intractable social rebel; a seemingly intractable problem in logistics. recalcitrant and refractory imply not only a lack of submissiveness but also an open, often violent, rebellion against authority or direction. Recalcitrant, the stronger of the two terms, suggests a stubborn and absolute noncompliance: a recalcitrant person, openly contemptuous of all authority. Refractory implies active, mulish disobedience, but leaves open the possibility of eventual compliance: refractory students, resisting efforts to interest them in their studies.
