I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">pond</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that pond can be written as pool)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for pool that I've seen before include "Shared supply; game" , "Pond; table game" , "American game resembling snooker" , "Ball game - small body of water" , "Game; common supply" .)
