<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">naturist</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that naturist can be written as nudist)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for nudist that I've seen before include "Sun worshipper" , "One who sheds clothes in camp or on beach" , "Streaker?" , "Person who believes in going unclothed" , "to cover nether regions - one wouldn't!" .)
