<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">or so</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for ish that I've seen before include "Suffix meaning like or characteristic of" , "Expiry (in Scots law)" , "loosely" .)
