I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">drinkable</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that drinkable can be written as potable)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for potable that I've seen before include "Drinkable" , "Fit for drinking" , "may be drunk" , "having healthy water quality" , "Non-toxic" .)
