<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">any minute now</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 soon that I've seen before include "Before you can say Jack Robinson" , "in a minute" , "Before long" , "Shortly" , "In the near future" .)
