Pause mark (5)
I believe the answer is:
comma
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">pause mark</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 comma that I've seen before include "Mark for smallest division of a sentence" , "its use may be divisive" , "part of list, invariably" , "breathtaking marking?" , "identifying place to breathe" .)
