<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">dagger signs</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for obeli that I've seen before include "Signs referring to footnotes" , "Marks on script" , "Textual marks" , "Textual indicators" , "Cross references" .)
