<span class="explanation-format__ClueExplanation">I believe this clue is a double definition.<br/ ><br/ >'<span class="explanation-format__original">declared</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that declared can be written as stated)</span><br/ ><br/ >'<span class="explanation-format__original">asserted</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ ></span>
(Other definitions for stated that I've seen before include "Declared or asserted" , "Said firmly, averred" , "Declared as fact" , "Expressed, detailed" , "Uttered, expressed in words" .)
