unruly

adj

Etymology: From Middle English unruly (“unquiet, restless”), equivalent to un- + rule + -ly (compare Middle English ruly, reuli (“subject to a religious rule, regular”)), but also representing a modified continuation of earlier Middle English unrouly, unroly (“unquiet, restless”), equivalent to un- + roolie. The latter is perhaps from or influenced by Old Norse *úróligr, related to Danish urolig (“restless”), Swedish orolig (“restless”), Icelandic órólegur (“agitated”). Compare also Middle English unroo, unro (“unrest”). More at roo.

1. Wild; uncontrolled.

   “The police gathered to contain the unruly mob.”

   “Unruly boys who will not grow up / Must be taken in hand / Unruly girls who will not settle down / They must be taken in hand”
