<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">indecorous</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that indecorous can be written as unseemly)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for unseemly that I've seen before include "Unbecoming, impolite" , "Unbecoming, not fitting" , "Indecent" , "Indecorous, unbecoming" , "Not decorous or fitting" .)
