I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">newcomer</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for parvenu that I've seen before include "One coming" , "One who climbs" , "Johnny-come-lately, upstart" , "One newly risen to wealth or power" , "An upstart, new arrival to society" .)
