unruly

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.
