<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">covered with water</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 awash that I've seen before include "Letting the 21 in" , "Letting in the sea" , "Level with the water surface" , "Flood" , "Flooded; about to sink" .)
