Clue, pointer (4)
I believe the answer is:
hint
<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">clue</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >'<span class="explanation-format__original">pointer</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ ></span>
(Other definitions for hint that I've seen before include "Imply, suggest" , "Taste" , "A dash" , "Tip - small amount" , "Piece of advice" .)
