I believe the answer is:
team
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">collaborative group</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for team that I've seen before include "People working together" , "One side in a game" , "Cooperating group" , "Squad; side" , "eleven?" .)
