I believe the answer is:
score
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">twenty</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for score that I've seen before include "purchase of illegal drugs" , "Hit - music" , "Tally; group of twenty" , "Tally; 20" , "musical work" .)
