<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">become known</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for emerge that I've seen before include "Come forth or appear" , "Come out or surface" , "Gradually come out" , "Come into existence" , "Come out or become known" .)
