I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">moneylender</span>' is the definition.<br/ ><span class="explanation-format__explanation">(a usurer is an exploitative moneylender)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for usurer that I've seen before include "Loan shark" , "He expects lots of interest" , "Shylock, for example" , "Extortionist" , "Shylock's profession" .)
