<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">solemn pronouncement</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for oath that I've seen before include "A solemn undertaking to tell the truth" , "It's taken in court" , "A curse - or a pledge" , "Solemn promise to tell the truth or be loyal" , "blasphemy" .)
