I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">swimmer</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that swimmer can be written as bather)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for bather that I've seen before include "man getting soaked?" , "one getting into the drink" , "Seaside swimmer" , "One dipping in the briny?" .)
