<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">waymark</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 signpost that I've seen before include "this will give you directions" , "Direction indicator" , "Postings (anag.)" , "It shows the way" , "Guide, indicator" .)
