<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">handler</span>' is the definition.<br/ ><span class="explanation-format__explanation">(tamer is a kind of handler)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for tamer that I've seen before include "less offensive?" , "Less wild" , "Animal trainer" , "Less arousing, exciting" .)
