Indicator (7)
I believe the answer is:
pointer
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">indicator</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that pointer is a type of indicator)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for pointer that I've seen before include "under control of mouse" , "The dog provides an indication" , "Dog; cursor" , "Indicator" , "Signpost - dog" .)
